Abstract: Contaminated solid acrylamide is purified by dissolving same in a C1- 5 aliphatic alcohol, optionally in the presence of polymerization inhibitors, separating the solution from the insoluble portion, and isolating solid acrylamide from the solution by lowering the temperature.

Abstract: The invention comprises compounds of the general formula in which R is an unsubstituted or halogensubstituted substituted alkyl, aryl (including alkaryl), aralkyl or cycloalkyl radical, R1 and R2 are alkyl radicals and R1 is a hydrogen atom or an amide group of the formula the radical R is as defined above and may bear one or two halogen atoms such as Cl or Br atoms. They may be obtained by reacting an isocyanate of the formula R-N = C = O, or a substance which will form such an isocyanate under the reaction conditions with an oxosulphoniumylide of the formula if desired in the presence of an inert solvent, at a temperature of from - 10 DEG C. to 100 DEG C. Suitable isocyanates are phenyl, p-tolyl, benzyl, methyl, ethyl, isopropyl, n-butyl, n-octadecyl, cyclohexyl, cyclododecyl, p - chlorophenyl, o-chlorophenyl, 4 - chloro - 3 - methylphenyl, 2-methyl cyclohexyl and b - chloroethyl isocyanates. The equivalent carbamyl chlorides e.g. those formed by reaction of a primary amine with phosgene, may be used instead of isocyanates. Suitable solvents are for example ethers, hydrocarbons, chlorohydrocarbons, N,N - dialkylsubstituted amides or lower fatty acids, N-alkyllactams or dialkyl sulphoxides. The products depend on the amounts of reactants used i.e. if an ylide is reacted with an isocyanate in the molar ratio of 0.5: 1 a substituted malonamide is obtained, but if the molar ratio is 1: 1 or an excess of isocyanate is used a mixture of the mono- and di-addition products is formed. The products are useful as intermediates for pharmaceuticals, dyes and pesticides. Malonic dianilide, p-chloroacetanilide, acetanilide, malonic acid-N,N1-butyldiamide and malonic acid-N,N1-isopropyl-diamide respectively are prepared by catalytic desulphurization with Raney nickel of the appropriate substituted oxosulphurylene amide.
