摘要： A process for preparing a methyl-blocked ethoxylate comprises heating at 180.degree.-320.degree. C., in the presence of a catalytically effective amount of a noble metal catalyst, an unsubstituted ethoxylate of 3 or more ethoxy units, or a monoalkyl-, monoaryl-, mono- or di-alkylamino- or mono- or di-arylamino ethoxylate of 2 or more ethoxy units, or a monoalkyl- or monoaryl-N,N-bis(ethoxylate) of 2 or more ethoxy units, all of which are derived from vicinal glycols, whereby there is prepared a corresponding methyl-blocked ethoxylate product which, for an unsubstituted ethoxylate starting material is a dimethylethoxylate having two fewer ethoxy units than the starting ethoxylate, and for the other ethoxylate starting materials, is a methylethoxylate having one less ethoxy unit in each ethoxylate group of the starting material.

摘要： A continuous process for the partial oxidation of methane to produce mixtures of formaldehyde and methanol wherein methane and an oxidizing gas are reacted in a reaction zone in the form of a flame and the resulting reaction mixture is cooled followed by separation of the resulting products, is further improved by controlling the velocity of the oxidizing gas so that it is 50 to 300 meters per second higher than the methane gas with the methane gas being introduced in a velocity of from 1 to 15 meters per second. Also, the stream of methane gas has a volume that is 3 to 100 times greater than the volume of the stream of oxidizing gas introduced into the reaction zone.

摘要： To produce methacrylic acid, firstly, isobutyraldehyde is acetalized. The resultant acetal is cleaved into the isobutenyl ether and alcohol. The isobutenyl ether is oxidized with molecular oxygen or an oxygen-containing gaseous mixture in the presence of an alkaline solution at temperatures of 30.degree.-70.degree. C. to obtain the epoxide. This epoxide is hydrolyzed to the .alpha.-hydroxyisobutyraldehyde. The latter is then oxidized with concentrated or fuming nitric acid at temperatures of 20.degree.-110.degree. C. to produce .alpha.-hydroxyisobutyric acid, and methacrylic acid is obtained therefrom by splitting off water.
摘要翻译：为了生产甲基丙烯酸，首先将异丁醛缩醛化。所得缩醛裂解成异丁烯基醚和醇。在碱性溶液存在下，在30〜70℃的温度下，异丁烯醚被分子氧或含氧气体混合物氧化，得到环氧化物。该环氧化物被水解成α-羟基异丁醛。然后将后者用浓度或发烟硝酸在20-110℃的温度下氧化，生成α-羟基异丁酸，通过分解水从其中得到甲基丙烯酸。
