    摘要: The invention relates to a method for producing pure alpha-alkoxy-Ω-hydroxy-polyalkylene glycols, creating small impurities of the product on high-molecular a-Ω-di-hydroxy-polyalkylene glycols. The method is based on the use of high-boiling initiator alcohols of the following general structure R2—(OCH2CHR)k—OH wherein R2 represents an alkyl radical comprising between 1 and 4 C atoms, preferably R2=CH3, k represents a number between 1 and 10, preferably between 1 and 4, and R represents H, CH3 or an alkyl radical comprising between 2 and 4 C atoms, preferably R=H, CH3. The use of the cited initiator alcohols enables the mixture of a basic catalyst and an initiator alcohol to be dried in such a way that it has a very low water content, and thus to produce very low concentrations of unwanted a-Ω-di-hydroxy-polyalkylene glycol impurities.

    摘要: The process described relates to the preparation of aqueous betaine solutions by reaction of a tertiary amine with an .omega.-monohalocarboxylic acid, preferably monochloroacetic acid, and an alkali metal hydroxide in the presence of water, which solutions are said to be highly pure particularly in respect of the tertiary starting amine and .omega.-monohalocarboxylic acid. This is achieved by first reacting the three reaction components in a certain molar ratio with the aim of obtaining a betaine solution which comprises only a tolerated amount of starting amine. This aqueous betaine solution is then treated with a sulfonating agent, preferably with an alkali metal sulfite, alkali metal pyrosulfite or alkali metal bisulfite, for conversion of the .omega.-monohalocarboxylic acid present into the corresponding sulfocarboxylic acid, which is not troublesome. The process described is simple to carry out and leads to the highly pure aqueous betaine solutions mentioned.
