Prepn. of branched fats by reacting unsatd. fats with vinyl cpds. - in presence of salt of transition metal or tin, esp. using fatty acid, fatty acid alkyl ester or fatty acid glyceride as unsatd. cpd.

摘要

Branched fats are prepd. by reacting (a) unsatd. fats with (b) vinyl cpds. in presence of salts of transition metals and/or Sn. Pref. cpds. (a) are fatty acids of formula R1CO-OH, fatty acid esters of formula R2CO-OR3, or fatty acid glycerol esters of formula (I), (where R1CO, R2CO, R4CO, R5CO, R6CO = 6-24C aliphatic acyl gps. with 1-5 C=C bonds; R3 = 1-4C alkyl). The vinyl cpds. have formula R7-CH=CH2 (II) in molar ratio of (a):(b) of 1:1-10. USE/ADVANTAGE = The prods. are used in prepn. of lubricants, corrosion inhibitors, surfactants, cosmetics, textiles and paper aids, and rolling and drawing oils. They lower the solidification point. Adducts are obtd. in high yield and selectivity.
