| abstract | 1283161 Butyl esters NIPPON SODA CO Ltd 16 April 1970 [21 April 1969 22 April 1969] 18278/70 Heading C2C Butyl ester mixtures are prepared from an aliphatic hydrocarbon mixture which is the residual fraction after the extraction of butadiene from a C 4 fraction produced by thermal or catalytic cracking of a petroleum stream or dehydrogenation of C 4 paraffins or olefines, by reaction with an aliphatic, cycloaliphatic and aromatic carboxylic acid or anhydride below 40‹ C. in the presence of an acidic catalyst to form tert-butyl ester, recovering the unreacted hydrocarbon reacting with a carboxylic acid at 60-120‹ C. under pressure in the presence of the acidic catalyst to form further butyl ester mixtures. The hydrocarbon mixture has the composition range, n-butane 1-50%, isobutane 1-20%, butene-1 10-60%, trans-butene-2 2-25%, cis-butene-2 1-25%, isobutylene 5-60%, butadiene 0À1-5% C 3 and C 5 fraction 0-5%. The acidic catalysts are sulphuric, phosphoric, polyphosphoric, silicic acids and boron trifluoride. The esterifying acids may be acetic, propionic, butyric, caproic, caprylic, capric, succinic, adipic, sebacic, tetrahydrophthalic, benzoic, p-oxybenzoic, phthalic, and trimellitic acids. |
