Ethyl alcohol substantially free from ether is produced by treating a mixture of ethylene and steam with sulphuric or phosphoric acid of 15--60 per cent strength at elevated temperatures and at 1000 lb pressure or more. The temperature may be 170--300 DEG C. and the pressure one to several...
the manufacture of perfumes, flavourings, or the like, or as parent materials in the manufacture of aldehydes, halogen derivatives, or the like, are produced from the esters of the corresponding carboxylic-acid derivatives, by reducing them by means of sodium and absolute ethyl or other alcohol....
The reaction is preferably carried out at a temperature of from 20 to 120 C. using a slight molar excess of the acylacetic ester. Examples describe the preparation of ethyl -butyl, -isobutyl and -methyl acetoacetates, 2-methylcyclohexyl -n-butylacetoacetate, ethyl -benzyl, -furfuryl, -ethyl...
This invention relates to the manufacture of hydration products of olefines, and especially to the manufacture of ethyl alcohol and/or diethyl ether from ethylene. I have found that hydration products of olefines may be produced by subjecting olefines to the successive and/or simultaneous... ...
申请(专利权)人: ICI LTD 发明人: MS Howarth 被引量: 12 摘要: m-Phenoxybenzyl esters of carboxylic acids are prepared from the methyl or ethyl esters of the acids by reaction of the latter with m- phenoxybenzyl alcohol in the presence of a tetra-aryl titanate as catalyst.收藏...
the invention relates to a new method for the production of partially known methylketonen formula in which r1, r2 and r3 in the description of the significance, using methyl seconds - alkyl ketones with halogeniden in the presence of a base and a diluent and in the presence of a phasentran...
Vapor-liquid equilibrium data were determined in a self-made still tested by Ellis at 99.80 kPa for isopropyl alcohol + ethyl benzene, isopropyl alcohol + ... RG Tardiff,BR Stern 被引量: 0发表: 1997年 Photochemistry of Di(4-pyridyl) ketone in isopropyl alcohol A series of sodium 2-sulfo...
Methyl and ethyl acetates are used widely as solvents, primarily for surface coatings. While use of synthesis gas is known as a building block in making a variety of chemicals there is no simple, direct, yet economical route toward production of glycol ester using relatively inexpensive catalysts...
PURPOSE:To produce the title copolymer excellent in appearance, clarity, weathering resistance, and pigment dispersion, by polymerizing a specific compound and an ethylenically unsaturated monomer in the presence of a fluoresin which has reactive double bonds via urethane linkages. CONSTITUTION:In the...
Various additives may be incorporated in the reaction mixture such as oxyethylated phenols, oxyethylated fatty alcohols as olezl alcohol, sulphated dimethyl oleate, polyalkylsiloxanes, polyalkylsiloxane-polyalkylene oxide copolymers, b -trichlorethylphosphate, antimony oxide, tricresyl phosphate, dio...
