  • Process for producing phthalimides of alkali metals
    Patent number: 4642354
    Abstract: A process for producing phthalimides of alkali metals by reacting phthalimide with an alcoholic solution of an alkali metal hydroxide and/or alcoholate, in which the molar ratio is equal to 1:1.03-1.1, while maintaining the alcohol concentration in the reaction mass within the range of from 10 to 60% by mass.

  • Method of producing acrolein
    Patent number: 4222965
    Abstract: A method of producing acrolein comprising evaporating acetaldehyde and formaldehyde in the presence of diphenyl-N-nitrosamine taken in an amount of from 0.1 to 3 wt. %. The resultant vapors of said aldehydes are fed for aldol condensation which occurs in a gaseous phase on a catalyst, viz., coarsely porous silica gel promoted by 10 to 12 wt. % sodium silicate at a temperature of from 270.degree. to 300.degree. C. in the presence of diphenyl-N-nitrosamine taken in a quantity of from 0.1 to 3 wt. %. The resultant gas mixture formed at the stage of aldol condensation, containing acrolein, acetaldehyde, formaldehyde and water is cooled to obtain a condensate. Said condensate is subjected to rectification in order to isolate a mixture of acrolein with acetaldehyde and water, and an aqueous formaldehyde solution. Said aqueous formaldehyde solution is concentrated and returned to the aforesaid evaporation stage.

  • Method of preparing isoprene and isoamylenes
    Patent number: 4147736
    Abstract: The method of preparing isoprene and isoamylenes consists in that a gaseous mixture of isobutylene and methyl alcohol is brought in contact with a catalyst, namely aluminum oxide or tantalum pentoxide, at a temperature of 250 to 500.degree. C. It is recommendable that use should be made of aluminum oxide modified with an oxide of at least one of the following elements: molybdenum, tungsten, chromium, zirconium, titanium, vanadium, and cobalt. Moreover, it is possible to use aluminum oxide modified with a sulphate of at least one of the following elements: zirconium and chromium. A combination of both modifications is also possible. The yield of isoprene obtained by the proposed method is 16 to 20 mol. percent, with respect to the passed methyl alcohol, and the yield of isoamylenes is 25 to 30 mol. percent.
