Abstract: Continuous production of substantially or wholly water-soluble esters of glycols or their monoethers with lower fatty acids by reaction of a glycol of the formula (I): HO-A-X (I) in which A is ethylene, propylene or butylene; and X is OH or OR in which R is alkyl of one to four carbon atoms or OAOH or OAOR in which A and R have the meanings given above with a lower saturated fatty acid at elevated temperature in the presence of a catalytic amount of a strong acid while continuously removing the water formed by means of an entrainer followed by treatment with an aqueous alkali. The glycol of the formula (I) is reacted in a first zone with the lower fatty acid, the water formed being distilled off as an azeotrope over the top by means of an entrainer, and the crude glycol ester including the entrainer is removed from the bottoms, mixes with an aqueous alkali, extracted in a second zone while supplying an extractant and water with phase separation and in a third zone the pure glycol ester is recovered from the resulting mixture of glycol ester, entrainer and extractant by rectification. Glycol esters are used as solvents for surface coating agents.
Abstract translation: 通过式（I）的二元醇：其中A是乙烯，丙烯或丁烯的HO-A-X（I）的反应连续生产二醇或其单醚与低级脂肪酸的基本上或完全水溶性的酯; 并且X是OH或OR，其中R是1-4个碳原子的烷基或OAOH或OAOR，其中A和R在较高饱和脂肪酸中具有上述含义，在催化剂量的强度存在下， 同时连续除去通过夹带剂形成的水，然后用碱水溶液处理。 式（I）的二醇在第一区域与低级脂肪酸反应，形成的水通过夹带剂在顶部作为共沸物蒸馏出来，并将包含夹带剂的粗乙醇酯从 底部，与碱水溶液混合，在第二区域中提取，同时提供萃取剂和进行相分离的水，在第三区域，通过精馏从所得到的乙二醇酯，夹带剂和萃取剂的混合物中回收纯乙二醇酯。 乙二醇酯用作表面涂层剂的溶剂。

Abstract: A process for the production of propionic acid which comprises the reaction of ethylene with carbon monoxide and water in the presence of a nickel carbonyl complex at a temperature of from 250 DEG to 320 DEG C in the liquid phase and at a pressure of from 100 to 300 atmospheres in a vertical cylindrical reaction zone, a gaseous zone being maintained at the upper end of the reaction zone and a bottom zone being maintained at the lower end of the reaction zone which is not in communication with said reaction zone over the entire cross section.

Abstract: Process for destroying organic halogen compounds, which are contained in dust-containing gases which have a carbon content of less than 0.6% by weight, by oxidative degradation with the aid of fixed catalysts suitable for this purpose, characterised in that a) the dust is separated off at 250 to 500 DEG C from the gases and the dust-free gas together with oxygen or an oxygen-containing gas is passed over the catalyst, or b) the dust is separated off below 250 DEG C, the organic halogen compounds are desorbed from the dust in an oxygen-containing gas stream at 250 to 500 DEG C and the gas stream is passed over the catalyst, or c) the dust-containing gas is passed over the catalyst in the presence of oxygen at 250 to 500 DEG C and the dust is then separated off.
