    Abstract: PROBLEM TO BE SOLVED: To provide a monoester of sulfosuccinic acid with faint smell. SOLUTION: A monoester of maleic acid obtained by reacting an oxide adduct represented by the general formula: RO-(AO)n-H (wherein, R is an 8-20C alkyl and/or alkenyl; A is a 2-4C alkylene; and n is an average number of 1-10), with maleic anhydride, and having >=96% conversion of the oxide adduct to the monoester, is reacted with a sulfonating agent such as an alkali metal salt of sulfurous acid in an amount regulated so that the ratio of the sulfonating agent to the monoester may be 1.10-1.30 in the presence of water in an inert gas atmosphere at

    Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing sulfosuccinic monoester of low odor. SOLUTION: This method of manufacturing sulfosuccinic monoester comprises the first step where an alcohol alkylene oxide adduct including specific proportions of alkali metal hydroxide and/or an alkali metal salt of an organic acid that are obtained by polyaddition polymerization of an alkylene oxide of 2-4 carbon atoms to an alcohol of 8-20 carbon atoms is allowed to react with maleic anhydride at a charge base molar ratio (maleic anhydride)/(the alcohol-alkylene oxide adduct) of 1.05-1.15 at a temperature of

    Abstract: PURPOSE:To obtain an odorless primary alcohol alkoxylate useful as a surfactant by adding either one compound of glycerin by adding either one of glyceric acids and specific compound to an aliphatic primary alcohol alkoxylate. CONSTITUTION:0.001-3wt.% of at least one kind of glyceric acids and salt thereof, compound [e.g. C2H5O(CH2CH2O)2CH2COOH] expressed by formula I [R is l-18C alkyl or alkenyl; A is 2-3C alkylene; n is 0-20 (as average value); m is 1-2] or salt thereof and compound expressed by formula II [X is H or -(CH2)mCOOH; (m is 1-2) and at least one among X of p+2 is -(CH2)mCOOH; p is 1-100] or salt thereof (e.g. 1mol carboxymethylated product of glycerin) is added to 6-30C aliphatic primary alcohol-alkoxylate to provide a high-quality primary alcohol-alkoxylate being odorless with the lapse of time.

    Abstract: PURPOSE: To obtain the subject deinking agent capable of giving deinked pulp of high whiteness with slight ink residues by mixing a specific compound with a reaction product from natural fat-and-oil, a polyhydric alcohol and an alkylene oxide in specified proportions. CONSTITUTION: This deinking agent is obtained by mixing (A) a compound of the formula [R1 is a (OH-substituted) 7-21C alkyl or alkenyl; R2 is H, a 1-22C alkyl, alkenyl or acyl; AO is a 2-4C oxyalkylene; (n) is such a number as to be
