Process for making polyol neoalkylester plasticizers from neo acids

A process for producing a neoalkylester plasticizer comprising:

• (i) drying a polyol feedstream;
• (ii) contacting the dried polyol feedstream with a CO recycle inerts purge stream to absorb BF3;
• (iii) pressurizing to 1500 to 2500 psig the contacted dried polyol feedstream, a branched olefin feedstream and a CO feedstream;
• (iv) combining the pressurized contacted dried polyol feedstream, the branched olefin feed stream and the CO feedstream in a reactor;
• (v) maintaining the reactor at a temperature of 20 to 80° C. for an effective amount of time to form a reactor effluent stream;
• (vi) flashing off BF3 and unreacted CO from the reactor effluent stream after the reactor to form a flashed reactor effluent stream;
• (vii) heating the flashed reactor effluent stream to remove unreacted branched olefin to form a crude neoalkylester plasticizer;
• and
• (viii) removing residual polyol, oligomers or other impurities from the crude neoester plasticizer to form a neoalkylester plasticizer, wherein the neoalkylester plasticizer is a triglyceride according to the formula
• wherein the sum of the carbons for the neoalkyl ester groups, defined as R1, R2, R3, R4, R5, R6, R7, R8, R9 plus the 3 carbons for the quaternary carbons bearing R1-R9 and the 3 carbons for the three carbonyl groups, and not including the 3 glycerol backbone carbons, ranges from 20 to 25;
• wherein the neoalkyl ester groups, defined as —C(R1)(R2)(R3), —C(R4)(R5)(R6), and —C(R7)(R8)(R9) groups, comprise C4 to C12 neoalkyl groups;
• and
• wherein R1, R2, R3, R4, R5, R6, R7, R8, R9 comprise C1-C9 alkyl groups.

A process for producing a neoalkylester plasticizer comprising:

• (i) contacting a crude glycerol or purified polyol feedstream with a neoacid feedstream in a reactor under effective temperature, pressure and time to form a neoalkylester plasticizer effluent stream, and
• (ii) purifying the neoalkylester plasticizer effluent stream to remove unreacted polyol, unreacted neoacid, and other impurities to form a neoalkylester plasticizer, wherein the neoalkylester plasticizer is a triglyceride according to the formula
• wherein the sum of the carbons for the neoalkyl ester groups, defined as R1, R2, R3, R4, R5, R6, R7, R8, R9 plus the 3 carbons for the quaternary carbons bearing R1-R9 and the 3 carbons for the three carbonyl groups, and not including the 3 glycerol backbone carbons, ranges from 20 to 25;
• wherein the neoalkyl ester groups, defined as —C(R1)(R2)(R3), —C(R4)(R5)(R6), and —C(R7)(R8)(R9), comprise C4 to C12 neoalkyl groups;
