Abstract: A method of preparing a polyolefin oil in the present invention comprises polymerizing an olefin having 6 or more carbon atoms in the presence of a mixture of a polyhydric alcohol derivative and an aluminum halide, said derivative being obtained by replacing hydrogen atoms of all the hydroxyl groups of the polyhydric alcohol by alkyl groups having 1-20 carbon atoms. The thus prepared polyolefin oil scarcely contains halogen, and it has a wide range of use such as, for instance, a lubricant, a cosmetic base, a textile finishing agent, etc.

Abstract: A method of manufacturing methallyl sulfonate, which comprises: forming a sulfur trioxide-dialkyl sulfoxide complex by effecting reaction between sulfur trioxide and dialkyl sulfoxide as mixed at the ratio of more than 0.8 mol of the latter to 1 mol of the former in the presence of an inert solvent; effecting reaction between said complex and isobutylene, in an amount of 0.9-1.2 mols of isobutylene per 1 mol of sulfur trioxide, by applying a temperature in the range of 10.degree.-80.degree.C; and neutralizing the reaction product with a base.

Abstract: In the method of manufacturing liquid polyol esters of carboxylic acid by making an olefin having 3 or more carbon atoms, carbon monoxide and polyhydric alcohol react with one another in the presence of a cobalt compound catalyst, the steps comprising heating the thus reacted mixture to distill out unreacted olefin and so forth, thereafter cooling the distillation residue and separating it into the ester of polyhydric alcohol and the cobalt compound.

Abstract: A neutralized product containing salt of .alpha.-sulfofatty acid ester in high concentration can be produced by the method comprising the steps of (1) sulfonating fatty acid ester by contacting a gaseous mixture of sulfur trioxide (SO.sub.3) and an inert gas containing 1 - 15% by volume of SO.sub.3 with a film of a fatty acid ester, said ester having the formula RCH.sub.2 COOR' (wherein R is alkyl having 8 - 18 carbon atoms and R' is alkyl having 1 - 5 carbon atoms), under the conditions that the molar ratio of SO.sub.3 to said fatty acid ester is in the range of 1.0 - 1.5, the temperature is in the range of 50.degree. - 85.degree.C and the time of contact is in the range of 0.5 - 30 seconds; (2) contacting a film of the reaction product obtained by step (1) into contact with said gaseous mixture, under the conditions of a temperature in the range of 95 - 150.degree.

Abstract: A method of manufacturing granular solid catalyst, comprising the process of mixing more than 1 mole of olefin and 1.0 - 1.2 mole of ketone having 4 or more carbon atoms relative to 1 mole of aluminum halide and effecting reaction at a temperature of more than 60.degree.C.

Abstract: A heavy-duty granular detergent composition consisting of 10 to 60 wt. percent of sodium citrate, 5 to 40 wt. percent of non-soap anionic surfactants, 0.1 to 10 wt. percent of inorganic aluminum salts and additives for use in conventional detergents, the weight ratio of the citrate to the surfactants being 1/5 to 10/1.

Abstract: An olefin oligomer having a low viscosity and a high viscosity index can be prepared by polymerizing an olefin having 6 or more carbon atoms in the presence of a mixture of a polyhydric alcohol derivative and an aluminum halide, said derivative being obtained by replacing the hydrogen atoms of all the hydroxyl groups of the polyhydric alcohol by either acyl groups exclusively or by acyl group and alkyl groups both of said groups having 1 - 20 carbon atoms. The thus prepared olefin oligomer scarcely contains halogen, and it has a wide range of uses such as, for instance, a lubricant, a cosmetic base, etc.

Abstract: A method for producing a liquid olefin polymer which comprises polymerizing an .alpha.-olefin having 6 - 14 carbon atoms or mixtures thereof, in the presence of a catalyst consisting of an alkali metal hydride, a halide of an element selected from boron and aluminum and a titanium halide, or a catalyst in which metallic lithium or sodium is added to those catalyst ingredients.

Abstract: A method of effecting polymerization of olefins having 6 or more carbon atoms or mixtures of such olefins (hereinafter referred to as the feed olefin), to produce a hydrocarbon liquid polymer which comprises mixing a catalyst composed of aluminum chloride, ketone having 4 or more carbon atoms and olefin catalyst constituent with 0.01 to 0.3 mole of ester, ether or alcohol per mole of said aluminum chloride and effecting the polymerization of the feed olefin at a reaction temperature of more than 60.degree.C.

Abstract: In the method of manufacturing carboxylic acids or esters thereof by reacting olefin, carbon monoxide and alcohol or water in the presence of catalyst prepared in advance by heating a cobalt compound and pyridine or at least one pyridine base selected from the group of mono-, di- and tri-alkyl (having 1.about.3 carbon atoms)-substituted pyridines under the pressure of carbon monoxide.
