Abstract

a-Pinene is the major compound in oil of turpentine that can be developed as the- starting material to synthesize compounds that have potential as organonitrogen ingredients through biological and physiological properties. Changes a-pinene into organonitrogen compounds can be carried out via addition reactions to the alkene group through Ritter reaction using acetonitrile or benzonitrile reagent. Carbocation rearrangement that occurs in reaction to direct the reaction products varies. a-Pinene reaction with acetonitrile to produce the compounds N-[1-Methyl-1-(4-methyl-cyclohex-3-enyl)-ethyl]-acetamide, N-(1,5-Dimethyl-1-vinyl-hex-4-enyl)-acetamide and N-(2,6,6-trimethyl-bicyclo[3.1.1] hept-2-yl)-acetamide. While a-pinene reactions with benzonitrile to produce the compounds of N-(1,5-Dimethyl-1-vinyl-hex-4-enyl)-benzamide and N-[1-Methyl-1-(4-methyl-cyclohex-3-enyl)-ethyl]-benzamide. Reaction products with ingredients benzonitrile (LC50 = 203.86 ppm) has a higher toxicity than acetonitrile-based reaction product (LC50 = 504.80 ppm) based on the test Brine Shrimp Lethality Test (BSLT).

Abstract

Increasing of air pollutions which are occurred in Indonesia is running together with the increase of motor vehicle populations. The old motor vehicles contribute to the increase of air pollution significantly due to the imperfectly burning process in their machine. Air pollution is seriously threat human being not only disturb human health but also cause greenhouse effect and global warming. It needs do some research to decrease air pollution caused by motor vehicle to get a better environment. The research has been done by filtration of disposal gas from motor vehicles using water, lubricant and carbonic acid as a filter. The disposal gas from a motor vehicle was flowed throw bottles contain of water, lubricant and carbonic acid. The result showed that water filter can decrease the disposal gas CO and CO2. Oil filter significantly decreased HC gas and carbonic acid filter could be used to decrease Pb.
