    Abstract: A beta-alkoxy-omega-lactam is prepared by subjecting to heating in the liquid phase an omega-amino-beta-alkoxy-carboxylic acid ester. The heating may be carried out at a temperature of 150* to 350*C. If the amino compound is prepared by hydrogenation of the corresponding cyano compound, it is not necessary to separate the amino compound from the reaction mixture. The lactams obtained may be applied for preparation of polyamides and copolyamides.

    Abstract translation: 通过在液相中加热ω-氨基-β-烷氧基 - 羧酸酯制备β-烷氧基-ω-内酰胺。 加热可以在150〜350℃的温度下进行。如果通过氢化相应的氰基化合物制备氨基化合物，则不需要将氨基化合物与反应混合物分离。 获得的内酰胺可以用于制备聚酰胺和共聚酰胺。

    Abstract: A process for the preparation of cycloalkanol by way of a two stage reaction from cycloalkene. The first reaction stage consists of reacting cycloalkene with sulphuric acid. The resultant adduct which is cycloalkyl hydrogen sulphate is separated from the reaction mixture by use of an inert solvent. The adduct is then hydrolyzed in the second reaction stage to product the cycloalkanol.
