  • Patent number: 8334323
    Abstract: Disclosed are compositions of the formula wherein R1 and R2 are each independently hydrogen or a linear or branched alkyl group containing from (1) to about (18) carbon atoms, provided that R1 and R2 together contain from about (8) to about (18) carbon atoms, and further provided that less than about 10 mole percent of R1 or R2 is hydrogen; R3 is hydrogen or an alkyl radical containing from (1) to about (6) carbon atoms; R4 and R5 are each independently hydrogen or an alkyl radical containing from (2) to about (6) carbon atoms, provided that R4 and R5 together contain from (2) to about (6) carbon atoms; m is an average value ranging from (0) to about (10), and n is an average value ranging from about (3) to (about 40), provided that the group containing m and the group containing n may be exchanged with one another as to position; and z is an average value ranging from about (0.5) to about (5).

  • Patent number: 8211949
    Abstract: Novel mixtures of long-chain (C10-C20) olefins are functionalized by conversion to aldehydes using an OXO process, or to sulfates, sulfonates, sulfones, sulfides, or sulfoxides by direct sulfonation. The aldehydes may then be hydrogenated to form alcohols, or aminated to form amines or amides. The olefins starting mixture may be acquired as a byproduct of the tetramerization of ethylene in the presence of certain chromium-containing tetramerization catalysts. The functionalized mixtures, and derivatives prepared therefrom such as alkoxylates prepared from the alcohols, may be useful as surfactants that may offer improved performance in many applications, while their preparation based on a byproduct mixture reduces their cost and also reduces waste-handling issues for this non-targeted stream.

  • Patent number: 7906474
    Abstract: Surfactant compositions that include one or more nonionic surfactants derived from seed oils and having a mixture of at least 8, 10 and 12 carbon atom linear alkyl moieties find use in a number of end use applications as substitutes for petroleum derived surfactants.
