Abstract

Butyl acetate (butyl ether of acetic acid) is the most common solvent in the production and use of paints and varnishes. Dissolves cellulose ethers, oils, fats, chlorinated rubbers, vinyl polymers, carbiol resins, etc. The addition of butyl acetate together with a small amount of butyl alcohol prevents whitening of the lacquer films. It is a fragrant substance that is part of fruit essences and perfume compositions. It is used in the tanning industry as a tannin. It is widely used in the pharmaceutical industry for the separation of primary substances in the production of antibiotics, etc

Abstract

Phosphorites S.K are the main phosphate raw materials for the factories of Uzbekistan producing phosphorus-containing fertilizers. The article presents the kinetics of decomposition of phosphorites S.K. sulfuric and extraction phosphoric acids. According to the data obtained, most of the phosphorite (52-65%) decomposes within 10 minutes, and then the process of opening the phosphate is sharply measured. With an equal total rate of acids, an increase in the proportion of sulfuric acid contributes to a deeper decomposition of phosphate. For 3 hours of interaction, an increase in the amount of sulfuric acid contributes to an increase in the degree of opening of the fossil raw material from 83.9 to 90.1%, at a process temperature of 80 ° C at 90 ° C from 89.8 to 93%.
