Abstract:
This invention describes processes to make products by cross metathesis of functionalized or non- functionalized olefins with poly-branched poly-olefins such as terpenes (e.g., farnesene(s), α-farnesene, β- farnesene, β-myrcene, etc.) and compositions made by such methods. More particularly, the present invention relates to methods of making (i) cross metathesis products by a cross metathesis reaction between at least one hydrovinylated olefinic substrate and at least one hydrovinylated cross metathesis substrate in the presence of at least one olefin metathesis catalyst; (ii) cross metathesis products by a cross metathesis reaction between at least one hydrovinylated olefinic substrate and at least one cross metathesis substrate in the presence of at least one olefin metathesis catalyst; and (iii) cross metathesis products by a cross metathesis reaction between at least one olefinic substrate and at least one hydrovinylated cross metathesis substrate in the presence of at least one olefin metathesis catalyst; as well as compositions made by such methods.

Processes for making C X to C Y olefins are provided. The processes include reacting a feedstock comprising C 5 and C 6 olefins under dimerization or oligomerization conditions to provide a dimerization or oligomerization product. The product is separated into a stream comprising unreacted C 5 and C 6 paraffins, a stream comprising C 10 to C X-1 olefins, and a stream comprising C X to C Y olefins, wherein X is at least 14 and Y is greater than X and less than or equal to 36.

Abstract:
The present invention is directed to alkylxylene sulfonate for enhanced oil recovery processes. The alkylxylene moiety in the alkylxylene sulfonate contains a high percentage of the 4-alkyl-1,2-dimethyl benzene isomer and a high percentage of alkyl group attachment to the xylene ring at positions higher than the 2-position on the alkyl carbon chain. The present invention is also directed to a method for enhancing the recovery of oil from a subterranean reservoir which method employs the alkylxylene sulfonate of the present invention. The alkylxylene sulfonate is employed in an aqueous media. The method optionally employs co-surfactants. It has surprisingly been discovered that the high percentage of the 4-alkyl-1,2-dimethyl benzene isomer and the high percentage alkyl group attachment to the xylene moiety at positions higher than the 2-position along the alkyl carbon chain on the alkylxylene sulfonate of the present invention provides an enhanced oil recovery (EOR) surfactant having low Interfacial Tension (IFT).

Abstract:
A process for producing phenyl-alkanes, the process comprising the steps of: a) passing a feed stream comprising a first concentration of a first acyclic paraffin having a carbon range of C 8 -C 28 and 2 or 3 primary carbon atoms and at least a second acyclic paraffin to an adsorption zone comprising a bed of an adsorbent comprising silicalite at adsorption promoting conditions to selectively adsorb at least a portion of the first acyclic paraffin contacting the bed of adsorbent with a desorbent stream comprising at least one component selected from the group consisting of a C 5 -C 8 cycloparaffin, a C 5 -C 8 normal paraffin, and a C 5 - C¿8 branched paraffin and recovering from the adsorption zone an adsorption extract having a second concentration of the first acyclic paraffin that is greater than the first concentration; b) passing at least a portion of the adsorption extract to a dehydrogenation zone, operating the dehydrogenation zone at dehydrogenation conditions sufficient to dehydrogenate the first acyclic paraffin and recovering from the dehydrogenation zone a dehydrogenated product stream comprising an acyclic monoolefin having a carbon range of C 8 -C 28 and 2 or 3 primary.carbon atoms; c) passing .a feedstock comprising a phenyl compound and passing at least a portion of the dehydrogenated product stream comprising the acyclic monoolefin to an alkylation zone, operating the alkylation zone at alkylation conditions sufficient to alkylate the phenyl compound with the acyclic monoolefin in the presence of an alkylation catalyst to form a phenyl-alkane comprising a molecule having one phenyl portion and one C 8 -C 28 aliphatic alkyl portion; wherein the aliphatic alkyl portion has 2 or 3 primary carbon atoms and no quaternary carbon atoms that are not bonded by a carbon-carbon bond with a carbon atom of the phenyl portion; and wherein the alkylation has a selectivity to 2-phenyl-alkanes of from 40 to 100 and a selectivity to internal quaternary phenyl-alkanes of less than 10; and recovering the phenyl-alkane from the alkylation zone.
Abstract:
A novel, storage-stable, free-flowing, solid product consisting essentially of an alkyl benzene sulphonic acid having 1 to 4 aliphatic carbon atoms and from 7 to 11 % water based on the weight of the product, said alkyl benzene sulphonic acid comprising at least 90 % by weight of a single isomer based on the total weight of organic material in the product, is prepared by drying a storage-unstable, solid alkyl benzene sulphonic acid having more than 11 % by weight water, said drying being effected at sub atmospheric pressure and at a temperature below the softening point of the product.
