Sulfited fatty compounds having a reduced content of free hydrogen sulfite are prepared by blowing unsaturated fatty compounds in an oxygen atmosphere at 100.degree. C. to 150.degree. C., sulfiting the blown fatty compounds with sodium metabisulfite, and subsequently fixing unreacted hydrogen sulfite as sulfosuccinic acid ester by aftertreatment with maleic acid esters, and optionally, a basic material.
摘要:
A process for improving the color and purity of dark-colored potassium or magnesium alkyl ester sulfonate surfactant compositions, and particularly alpha-sulfo fatty acid methyl ester compositions, without the need for bleaching or other process steps. The process comprises the steps of (1) forming a mixture comprising (i) an alkyl ester sulfonate surfactant composition containing impurities including dark-colored impurities, organic and inorganic salts, and disalts, and (ii) water, and (2) separating the ester sulfonate surfactant from the mixture. The process may further comprise step (3) recovering the alkyl ester sulfonate surfactant. Methyl ester sulfonate surfactant compositions are most preferred. After processing in accordance with the invention, the alkyl ester sulfonate surfactant composition has improved color, purity, and odor properties.

摘要:
In light colored surfactants produced by sulfonation of fatty acid alkyl esters with less than 2 moles of SO.sub.3 per mole of fatty acid alkyl ester and subsequent work-up of the crude sulfonate in aqueous medium to form salts, the content of .alpha.-sulfofatty acid disalts is regulated and reduced by transesterifying the sulfonation product before its treatment with an aqueous medium with at least about 0.5 mole equivalent of an alcohol, based on the SO.sub.3 which is not for .alpha.-sulfonation.

A mixture of a saturated fatty acid ester sulfonate and an unsaturated fatty acid ester sulfonate, which is useful as an active ingredient of a detergent, is prepared at a stroke by sulfonating a mixture of a saturated fatty acid ester and an unsaturated fatty acid ester by using as a sulfonating agent a saturated fatty acid ester having SO.sub.3 adsorbed therein in an amount larger than the equimolar amount, and then neutralizing the sulfonation product.
摘要:
Aqueous concentrates of alkali metal salts of .alpha.-sulfonated fatty acid alkyl esters (ester sulfonate salts) which are pumpable at temperatures of at least 60.degree. C. are obtained without the addition of viscosity regulators by preparing pastes containing at least about 60% by weight of ester sulfonate salts derived from C.sub.16 and/or C.sub.18 fatty acids. More particularly, the concentrates contain less than 10 mole % of ester sulfonate salts with fatty acids containing fewer than 16 carbon atoms. The concentrates are obtained by neutralizing the crude ester sulfonates with concentrated alkali hydroxide solution with intensive cooling at temperatures of at most 90.degree. C.
