Abstract: A method is disclosed for manufacturing surfactants for utilization in petroleum industry operations. The method comprises providing a bio-lipid. The bio-lipid can include one or more medium-chain or long-chain fatty acids, such as Lauric acid, Myristic acid, Palmitic acid, Stearic acid, Palmitoleic acid, Oleic acid, Ricinoleic acid, Vaccenic acid, Linoleic acid, Alpha-Linoleic acid, or Gamma-Linolenic acid. Fatty acid alkyl esters are produced by reacting the bio-lipid with a low-molecular weight alcohol. The fatty acid alkyl esters are reduced to a fatty alcohol. The fatty alcohol is dimerized to form a Guerbet alcohol, which is a precursor to producing surfactant for utilization in a petroleum industry operation, such as an enhanced oil recovery process.

Abstract: This invention describes a safe method for the production of sulfamoyl chloride from chlorosulfonyl isocyanate and formic acid in the presence of a amide catalyst, taming the hazardous nature of this reaction by circumventing heat accumulation processes, as well as the sulfamoylation of alcohols and phenols with the resulting sulfamoyl chloride in N,N-dimethyl acetamide or N-methyl pyrrolidone thereby avoiding the formation of side-products which were inevitable with the methods of the prior art using dimethyl formamide or dichloromethane as a solvent. The current invention allows industrial scale applications and describes as an example the process of manufacture of the biologically active compound 17&bgr;-Hydroxyestra-1,3,5(10)-triene-3-yl sulfamate.

Abstract: A method for preparing a sulfonated compound with minimal or no waste products using a porous inorganic material absorber. The absorber is saturated with a compound to be sulfonated and then contacted with a sulfonating gas mixture to form a sulfonated product. After forming the sulfonated product, excess sulfonating gas is removed by contacting the sulfonated product with warm air. The sulfonated product is then neutralized and the product is removed with water from the inorganic material absorber. The absorber is then dried with hot air so that it may be reused for future sulfonation processes. The process results in preparation of a sulfonated compound having inorganic salts present in an amount less than about 1.0 percent by weight based on total sulfonated product weight. The process results in highly effective sulfonation of a compound with formation of little or no waste materials, particularly waste materials such as solvents and undesirable inorganic salts.
