    摘要： Isobutylene is separated from a stream of C.sub.4 hydrocarbons containing it and remarkable amounts of butadiene, and methyl tert-butyl ether is prepared, by feeding that stream of hydrocarbons and methanol to a reactor containing a catalyst consisting of an acid ion-exchange resin, maintained at a temperature in the range of from 60.degree. to 120.degree. C, at a space velocity (LHSV) in the range of from 5 to 35, the relation between the space velocity (LHSV) and temperature being correlated to correspond to the formula: LHSV = 1/2t - 25, wherein t is the temperature in degrees C, so that the isobutylene and methanol are caused to react, and then separating the methyl tert-butyl ether thus formed from the reaction mixture by distillation.

    摘要： Dimethyl carbonate and methyl tert-butyl ether are prepared by a continuous integrated process comprising:a) feeding methanol, carbon monoxide and oxygen into a reaction environment maintained under methanol oxidative carbonylation conditions, to form a liquid reaction mixture containing dimethyl carbonate and unaltered methanol;b) at least partly eliminating the water from the reaction mixture of stage a);c) feeding the dehydrated mixture of stage b) and isobutene, or a hydrocarbon fraction containing isobutene, into a reaction environment maintained under etherification conditions, to form a liquid reaction mixture containing dimethyl carbonate and methyl tert-butyl ether; andd) recovering the dimethyl carbonate and methyl tert-butyl ether from the reaction mixture of stage c).

    摘要： Methyl tert-butyl ether is prepared, and a stream of hydrocarbons containing isobutylene is freed therefrom, by reacting the isobutylene with methanol in a two stage process wherein, in the first stage, a stream of hydrocarbons containing isobutylene and methanol is fed to a primary reaction zone where the isobutylene and methanol partially react in the temperature range of from 50.degree. to 90.degree.C and at a pressure of from 10 to 30 atmospheres in the presence of a catalyst to form methyl tert-butyl ether which is separated by distillation from the residue of isobutylene and methanol and all other hydrocarbons in the feed stream, and, in a second stage, the residue of isobutylene and methanol and other hydrocarbons is fed to a secondary reaction zone where the residue of isobutylene and methanol react in the vapor phase, at a temperature in the range of 60.degree. to 100.degree.C and a pressure of from 15 to 40 atmospheres in the presence of a catalyst consisting of an acid ion exchange resin, to form the balance of methyl tert-butyl ether which is recovered by distillation to leave a balance of other hydrocarbons practically free from isobutylene.

    摘要： A process for producing methanol from synthesis gas in the liquid phase is disclosed, which comprises reacting CO with H.sub.2 in the presence of a catalytic system constituted by one or more copper compound(s) and one or more alkali metal and/or alkali-earth metal alkoxide(s), in the presence of one or more solvent(s), the basic features of which are in that to the reaction methanol and one or more alkyl formate(s) are added, with the process being carried out with a concentration of the catalytic system in the solution constituted by the solvents and the same catalytic system, which is comprised within the range of from 0.001 to 1 molar for the compound(s) of copper, and is comprised within the range of from 0.01 to 5 molar for the alkali metal and/or alkali-earth metal alkoxide(s), and at a temperature higher than 40.degree.
