    Abstract: PROBLEM TO BE SOLVED: To provide a method for purifying N-vinylformamide capable of producing high-quality N-vinylformamide for making a polymer having especially high molecular weight having a K value by Fikentscher's method larger than 200. SOLUTION: This N-vinylformamide distillate is obtained by fractional distillation of N-formamide using a column under reduced pressure. The distillation is continuously carried out in the presence of formamide under 0.5-30 millibar measured at the top of the column. The distillation is controlled so that N- vinylformamide having 1-6wt.% formamide content as the distillate is obtained to give the objective N-vinylformamide for producing an N-vinylformamide polymer having a K value larger than 200, containing 1-6wt.% formamide.

    Abstract: PROBLEM TO BE SOLVED: To provide a catalyst which is suitable for the reaction of a carboxylic ester with an alkylene oxide and enables to produce a desired alkylpolyalkylene glycol carboxylate under a mild reaction condition without any undesirable byproduct formed. SOLUTION: The alkylpolyalkylene glycol carboxylate can be produced by a method comprising a process for reacting a carboxylic ester with an alkylene oxide in the presence of a multimetal cyanide compound as a catalyst represented by formula (I): M 2 M a [M (CN)b (A)c ]d fM g Xn mM p Yq h(H2 O)eLkP, for example, by formula (II): M Fe[Fe(CN)6 ]nH2 O [wherein M is a potassium ion (K ) or an ammonium ion (NH4 )]; and can be used as a raw material for a concrete fluidizing polymer.

    Abstract: The invention relates to a method for producing compounds of general formula (IIb), wherein R represents C6-C30 alkyl or C6-C30 alkenyl which can also support up to 5 hydroxyl groups, formyl groups, C1-C4 alkoxy groups, phenoxy groups or C1-C4 alkoxycarbonyl groups as substituents and which can be interrupted by up to 5 non-adjacent oxygen atoms, or alkoxylate groupings of formula -(CH2)k-O-(A O)m-(A O)n - Y, wherein A and A represent 1,2 alkylene groups with 2 to 4 C-atoms, Y represents hydrogen, C1-C12 alkyl, phenyl, or C1-C4 alkoxycarbonyl, k represents the number 1, 2 or 3 and m and n each represent numbers from 0 to 50, the sum of m and n being at least 4, independently of each other. According to the inventive method, iminodiacetonitrile is reacted with aldehydes of general formula R-CHO and HCN or alkali cyanides. The method is carried out a) without using an organic solvent and in the presence of a Lewis or Bronsted acid, or b) with or without an organic solvent and in the presence of an emulsifier, or c) with or without an organic solvent and at a pressure of 1 to 40 bar.
