摘要:
An Alpha , omega -glycol, a primary alcohol or an aliphatic compound having one or two secondary alcohol groups is dissolved in a solvent. The resulting solution is heated to 10* - 70*C and brought into contact with an ozone-containing gas. Then, the solution is elevated to 70* - 110*C and brought into contact with an oxygen-containing gas. By thus oxidizing the starting material, there is formed in the solution a dibasic acid or a fatty acid; the former acid occurs where the starting material being used is an Alpha , omega -glycol and the latter acid occurs where it is either a primary alcohol or an aliphatic compound having one or two secondary alcohol groups. The dibasic acid or fatty acid thus formed within the solution can be isolated by removing the solvent from the solution.
摘要:
Thallous salts of Beta -dicarbonyl compounds, prepared by reaction of the Beta -dicarbonyl compounds with a thallous alkoxide, are treated with alkyl halides to give C-alkyl products in high yield, with acyl halides at room temperature to give Caryl products, and with acyl halides at low temperatures to give O-acyl products. Thallous phenolates are esterfied with acyl or aroyl halides. Anhydrides are also prepared, as are biaryls and bi-sec-alkyls. N-Heterocyclics, including purines and pyrimidines, are N-alkylated. Lactams are O-acylated or Nalkylated.
摘要:
THE PRESENT INVENTION RELATES TO A PROCESS FOR THE PREPARATION OF CARBOXYLIC ACIDS AND ESTERS, SPECIFICALLY BY THE REACTION OF ALCOHOLS OR THE ESTER, ETHER AND HALIDE DERIVATIVES THEREOF, WITH CARBON MONOXIDE IN THE PRESENCE OF CATALYST SYSTEMS CONTAINING AS ACTIVE CONSTITUENTS A RHODIUM COMPONENT AND A HALOGEN COMPONENT. THE PROCESS IS ALSO DIRECTED TO THE PRODUCTION OF MIXTURES OF ORGANIC ACIDS AND/OR ORGANIC ESTERS.
摘要:
A PROCESS FOR MAKING ACID METAL SALTS FROM ORGANIC HYDROXYL COMPOUNDS COMPRISING MIXING WATER AND A CATALYST COMPRISING PALLADIUM ON INERT SUPPORT MATERIAL IN A REACTOR, AGITATING THE MIXTURE TO PRODUCE A UNIFORM CATALYST SUSPENSION, ADMIXING WITH THE CATALYST SUSPENSION THE HYDROXYL COMPOUND TO BE CONVERTED, INJECTING OXYGEN INTO THE MIXTURE, AND ADMITTING A METAL HYDROXIDE TO THE REACTOR, TO CONVERT SUBSTANTIALLY ALL OF THE HYDROXYL COMPOUND TO ITS CORRESPONDING ORGANIC ACID METAL SALT.
