Esters of branched C9 alcohols suitable as plasticizers are formed by esterification of a C9 alcohol produced by the aldol condensation from propanal and a C6 aldehyde and hydrogenation, the propanal optionally having been made from natural gas streams.
A composition comprising a C6 aldehyde and a saturated aliphatic C9 aldehyde made by subjecting a saturated C6 aldehyde to an aldol condensation with propanal to form a product comprising an unsated C9 aldehyde, and hydrogenating the unsaturated aldehyde to a saturated C9 aldehyde, wherein said composition contains greater than 35 percent C9 aldehydes on a C9 and higher aldehyde basis.
An ester formed from 2,4dimethylheptanol, other than a mixed ester of 1,2-benzenedicarboxylic acid with said 2,4dimethylheptanol and a saturated C8, C9 or C10 primary alkanol.
A plasticizer composition comprising an ester made from a polybasic acid and an alkanol blend, said alkanol blend comprising at least 50 percent of 2,4-dimethylheptanol and less than 50 percent of a compound selected from the group consisting of 2-methylpentanol, 2,4,6-trimethylnonanol, and combinations thereof.
A plasticizer composition comprising an ester made from a polybasic acid and an alkanol blend other than a plasticizer composition consisting of the mixed ester of 2,4-dimethylheptyl and 4,6-dimethylheptyl alcohols with 1,2-benzenedicarboxylic acid, said alkanol blend comprising at least 5 percent by weight of 2,4dimethylheptanol and correspondingly at most 95 percent by weight of another alkanol or alkanols having from 6 to 12 carbon atoms.
A refrigerant fluid comprising:
A synthetic lubricant, comprising:
An ester formed from 2,4dimethylheptanoic acid and an alcohol, wherein said alcohol contains at least two carbon atoms and only one hydroxyl group.
An ester formed from 2,4-dimethylheptanoic acid and an alcohol other than a tetraester of pentaerythritol, 2-methyl-hexanoic acid and 2,4dimethylheptanoic acid;
An ester formed from 2,4-dimethylheptanol, other than a mixed ester formed from 1,2-benzenedicarboxylic acid, said 2,4dimethylheptanol and a compound selected from the group consisting of C8 primary alcohols, C9 primary alcohols other than said 2,4-dimethylheptanol, and C10 primary alcohols.
A mixture comprising an ester, wherein said ester is formed from an alcohol mixture containing greater that 5 percent by weight of 2,4-dimethylheptanol.
