摘要:
Improved process for the production of alkyl sulphonic acid hydroxy alkyl amides by reacting alkyl sulphonic acid chlorides and hydroxy alkyl amines in the presence of acid binding agents wherein aqueous alkali hydroxide solution is used as acid-binding agent, the three components are applied in a substantially stoichiometric ratio, and the reaction is carried out by adding the alkyl sulphonic acid chloride to the hydroxy alkyl amine and adding to the mixture thus obtained the aqueous alkali hydroxide solutions at such a rate that the pH-value of the reaction mixture does not exceed pH 10.

摘要:
A coating composition comprising as binder a reaction product of a polyepoxide with more than one 1,2-epoxide group per molecule, wherein its epoxide groups have been reactedA. with 0.01 to 0.5 NH-equivalents, based on one epoxide equivalent, of ammonia or of an aliphatic or cycloaliphatic primary or secondary amine or of an amino carboxylic acid or of a mixture of the aforementioned nitrogen compounds; and subsequentlyB. with 0.40 to 0.90 carboxyl equivalents, based on one epoxide equivalent, of acrylic acid or methacrylic acid or of a mixture of acrylic amd methacrylic acid; and finallyC. with 0.09 to 0.50 carboxyl equivalents, based on one epoxide group, of a saturated aliphatic, a cycloaliphatic or an aromatic carboxylic acid, so that at least 80% of the epoxide groups originally present have been reacted through these three component stages. The binder may be used alone or together with additional monomers by radicals forming compounds or preferably by photopolymerization in the presence of a photoinitiator.

An improvement in a process for the preparation of a pinacol of the formula ##STR1## wherein R.sup.1 and R.sup.2 are identical or different and represent optionally substituted aliphatic, cycloaliphatic, araliphatic or an aromatic hydrocarbon radical by reducing a ketone of the formula ##STR2## wherein R.sup.1 and R.sup.2 have the abovementioned meanings with a base metal, the improvement comprising carrying out the reduction in the presence of an organic halogen compound and in the presence of a phosphoric acid amide, phosphoric acid ester and/or carboxylic acid amide.
摘要:
Certain new monosilyl ethers have virtually no effect on the storage stability of unsaturated polyester resins at temperatures up to 70.degree. C, but at higher temperatures effect rapid curing to give polymers which are substantially monomer-free.
