Title:
NEO CARBOXYLIC ACIDS AND A PROCESS FOR THEIR PREPARATION
Document Type and Number:
WIPO Patent Application WO2000007971
Kind Code:
B1
Abstract:
An isomeric mixture comprising isomers represented by the formula: R1R2R3C'-COY where R1R2R3C'- has a neo structure about the C' atom; R1, R2 and R3 are independently hydrocarbyl groups each having from 1 to 10 carbon atoms and the number of carbon atoms in R1, R2 and R3 ranges from 7 to 12; Y is selected from the group consisting of -OH, -OM, -X, -OR4, -OOR5, OOCO-CR6R7R8 and -NR9R10 where M is selected from the group consisting of lithium, sodium, potassium, cesium, calcium, cobalt, quaternary ammonium, manganese, copper, barium, zinc, magnesium and tin; X is selected from the group consisting of a halogen or non-halogen leaving group; R4 is selected from the group consisting of a linear, branched or cyclic hydrocarbyl of 1 to 28 carbon atoms, a linear, branched or cyclic hydroxy hydrocarbyl of 1 to 28 carbon atoms, a linear, branched or cyclic dihydroxy hydrocarbyl of 1 to 28 carbon atoms, glycidyl and polyether; R5 is a linear, branched or cyclic alkyl of 1 to 28 carbon atoms; each of R6, R7 and R8 is independently selected from the group consisting of hydrogen and a linear, branched or cyclic hydrocarbyl of 1 to 28 carbon atoms; and each of R9 and R10 is independently selected from the group consisting of hydrogen and a linear, branched or cyclic hydrocarbyl of 1 to 28 carbon atoms; and at least 40 % by weight of the isomers have a total of 10 carbon atoms in R1, R2 and R3. Specifically the present invention is directed to a neo C9 to C14 carboxylic acid mixture and derivatives thereof, and a method for manufacturing such mixtures.
