Abstract

Vetiver oil is one of the essential oils which are use as perfumeand fragrance material.It has a pleasant odour and a typical charateristic as a fixative agent in perfumes.An oil which has high vetiverol content is usually more appreciated and highly valued.An attempt to perform and high vetivero content from vetiver root by manipulating the time and rate of distillation has been carried out.It was observed that the longer the distillation was proceeded a higher yield of oil and vetiverol content was discovered.Rate of distillation seemed to have he same effect,the faster distillation was taken place, more oil and higher vetiverol was found.

Abstract

Acetone-butanol-etanol (ABE) mixture in fermentation broth drived from fermentation of empty bunch of palm fruit is still containing butyric and acetic acid.The mixture can be separated by into its components byfractional distillation based on their different boilling points.The presence of butyric and acetic acid in the broth liquid did not interfere the yield of distillation. It was beneficial to concentrate the ABE content before the real fractional distillation was taken place.By collecting 12% of the liquid through a simple distillation had increased the concentration of ABE mixture from 17.42 to 125.25g/1.Fractionation of concentrated ABE mixture at 45 to 65 degree C on 3:1 reflux ratio produced aceton with concentration 554.63 g/1 and purity 70.22% while those of etanol at 78 to 81 C on  30:1 reflux ratio produced 424.73 g/1 and purity 53.61%.The residue was consist of water and and water was distilled like a stem distillation,since butanol has higher boiling point than water and the distillate was separated base on their different density.The yield of butanol 709.15 g/1 and purity 87.57%.

Abstract

The derivation of alpha-pinene into various compound had been studied for many years. The transformation of pinene into camphene was carried out by hydrochlorination process. The process waas in fluenced by several conditions such as temperature, time of reaction and the atmospheric pressure. When the temperature and atmospheric pressure had been fixed, the time of hydrochlorination have a great effect. It was found that oversaturated condition of HCl gas reduced the camphene yield. The optimum time of hydrochlorination process was 30 minutes if 50 ml of alpha-pinene was bubble with HCl gas at the rate of 20 ml perminute on standard condition.

Abstract

Essential oils are volatile derived from plants, therefore Glc method of analysis is most recommended.Each oil have differentcomponents and quantitatively can be used as a standard if the same procedure is followed.In case from the different sample different"finger print" was found,the sample might be suspected to had been adulterated. The physico chemical constant of the oils are also described in this paper, hence it can be used as a standard for most indonesian commercial oils.

Abstract

Terpinol is one of the compounds which are terpene used as flavorand fragrance materials.In nature it is found in more than 200 derivatives from leaves,herbs and flowers.Syntheticaly it can be prepared from terpene hydrate which are derived from alpha-pinene trough its reaction with sulphuric acid,acetic glacialand aceton.It was observed that when alpha-pinene reacted with sulphuric acid,acetic glacial andaceton in 50:60:10 and 45 ratio,62% alpha-pinene was converted into alpha-terpineol.The contents of alpha-terpineol can also be observed from its refractives indexes and specific gravities,the higher the content had increased the values.

Abstract

Kapol and kapolaga are the local name in indonesia for cardamom.Although their botanical name has already clear for each species,nevertheless there were stil some confusions in regional name.Some people call it kapol for kapolaga on in turn kapolaga was called  kapol. An attempt tom distinguish which is which a GLC analysis on their essential oils were determined.From the result it distinctly can be recognised due to their GLC finger print didi not match each other so their composition were not the same. Kapol oil was totally different from kapolaga oil since its main component was 1,8-cineol,while kapolaga oil contained 1,8-cineol,terpinil acetate and geralsacetate at its main component.According to perseglove (1981)the first was belong to ammomum cardamomum and the latter was belong to Elletaria cardamomum.Since the letter type was more popular and reqodnised in international market,the first type was called as false cardamon. This is no fair since every type of cardamun had their own application and market.The result of this study willbe used as data to support the international standartd organitation (ISO) proposal.

Abstract

Vetiver oil is obtained by distillation. Due to the high cost of production and too small profit margin, farmers tend to reduce the distilling time to a third of its usual practice; e.g. from 36 hours to 12 hours. Young harvested root has also been used now to reduce the cost. All those practices tend to have had influence to the quality of the vetiver oil. Improvements through distillation process and harvesting method seemed need a rather long period. A short cut practice to improve the quality has been carried out by deterpenation process. The result showed that by means of fractional distillation and rejecting the low boiling pint terpenes up to 30% has raised the value of ester number, ester number after acetylation and vetiverol content from 8.17; 119.3 and 46.8% to 13.1; 128.9 and 50.6% respectively.

Abstract

Study on the effects of agitating duration and the ratio of sulphuric acid on the preparation of sulphated shark oil as fat liquor had been carried out .the aimof the experiment was to introduce sulphuric acid that will be absorbed into the molecule chain of fatty acid cpmpletely and produced sulphated oil .the experiment was conducted in there variables of agitating duration (A) i.e:4,5 and 6 hours and the ration of sulphuric acid introduced and the ration of acid/oil was : agitationfor 6 hours and 40% of sulphuric acid ration or A3B3 combination .the sulphated oil has 96.77 lodine number saponification number 209.68 and 1.665 fixed S03 .the lower lodine number showed most double bond chain of the oil had been occupied by sulphate groups ,the higher saponification numbershowed the amout of sulphate group in the fatty oil chain ,the same as showed by the fixed S03 .it is concluded that agitating duration or mixing time and ratio sulphuric  acid to the shark liver oil to give significant effect on sulphated shark liver oil formed.

Abstract

Alpha pinena is the main component of turpentine oil. This compound is very important since its derivates are used in various indutsries. It may be transformed into borneol, iso-borneol, citronellol and geraniol through an acid reaction which are used in parfumery or it mey be oxidised to pinic and pinonic acid which are used in polymer industry. The isolation of a-pinena from turpentine oil has long been know for centuries, unfortunately no one has discussed it in detail. The aim of this experiments is to find out a suitable condition during the isolation especially the value of reflux ratio if a fractional distillation process is undertaken. By using an Oldershaw type fractional column equipped with five perforated plates it was found that 1:3 ratio was the optimum condition. Not less than 80% of a-pinena with 96% purity had been isolated by this method from a commercial turpentine oil.

Abstract

 Anethol that is used in flavor, fragrance and medicine is the main component of anise oil. Pure antehol has melting point around 21.6 to 22 derajat celcius that is close to room temperature. An attempt to isolate anethole from Star anise oil (Illicum verum) a studied through freezing process has been done. It was found when the oil was cooled to 12 derajat celcius almost all the oil was solidified. The crystal contains 89% anethole that is not pore enough. When the oil was cooled at 14 derajat and 16 derajat celcius, 30% and 7% of the oil was crystallized respectively and contained 90% and 94% anethole. The experiment showed the lower the temperature, the least pure anethole was collected. A technique to isolate anethole from star anise oil can be done by fractional crystallization.
