Isobutyl acetate succinate

In this way they prepared butyric ethyl ester from potassium acetate and potassium-ethyl succinate. The synthesis of the ethyl ester of valeric, capronic, and isobutyl-acetic acid was also effected. 

Tills is generally associated with the familiar alcoholic fermentation in which theoretically 100 parts of glucose are converted to 51.1 parts of ethyl alcohol (ethanol). 48.9 parts of carbon dioxide (CO/i. and heat. In addition, however, the anaerobic reaction also yields minor byproducts in small amounts—mainly glycerol, succinic acid, higher alcohols (fusel oil), 2,3-butanediol, and traces of acetaldehyde, acetic acid, and lactic acid. Fusel oil is a mixture of alcohols, including -propyl, -butyl, isobutyl, amyl, and isoamyl alcohols. 

Three systems were selected and their properties published (Misek, 1979). These are water-toluene-acetone, water-methyl isobutyl-ketone (MIBK)-acetic acid and water-butanol-succinic acid, representing systems with high, medium and low interfacial tensions respectively. 

Esters constituted the largest family and included acetates (ethyl, propyl, isobutyl, butyl, isoamyl, and phenethyl), ethyl esters of fatty acids (propanoate, isobutanoate, butanoate, hexanoate, octanoate, 3-hydroxybutanoate, 3-hydroxyhexanoate and furcate), ethyl esters of organic acids (pyruvate, lactate, ethyl myristate, diethyl malate and, mono- and diethyl succinate) and various other esters, such as methyl butanoate, isobutyl lactate and phenylethyl octanoate. The acids quantified included isobutanoic, butanoic, hexanoic, octanoic, decanoic, lauiic and 3-methylbutanoic. The lactones included y-butyrolactone, pantolactone, y-decalactone and E- and Z-oak lactone and the terpenes included neral d-terpineol, P-dtronellol and Z-nerolidol. The aldehyde family comprised acetaldehyde, benzaldehyde, furfural, 5-methylfurfural and octanal, and the phenol family included eugenol, 4-ethylphenol and 4-ethylguaiacol. Finally, 1,1-diethoxyethane, acetoin, sotolon, 2, 3-butanedione, p-cymene and methionol were also determined.
