Abstract:
A PROCESS IS DESCRIBED FOR THE RECOVERY OF FERTILIZER GRADE AMMONIUM SALTS IN HIGH YIELDS FROM ACRYLONITRILE WASTE WATER PROCESS STREAMS CONTAINING WATER-SOLUBLE ORGANIC TARS BY THE REMOVAL OF WATER AND VOLATILE ORGANIC MATTER FROM THE WASTE WATER PROCESS STREAMS IN THE PRESENCE OF A WATER MISCIBLE SOLVENT, RECOVERING THE SOLID AMMONIUM SALT FROM THE RESIDUAL AMMONIUM SALT-SOLVENT-TAR MIXTURE AND RECOVERING THE SOLVENT FOR RE-USE.
Abstract:
A Motor fuel is provided which comprises a blend of (1) a mixture of hydrocarbons boiling within the gasoline range, and (2) an aryl ether boiling with the gasoline range, the aryl ether having the structure: R1 - (R2)n - O - R3 wherein R1 is selected from the group consisting of phenyl, substituted phenyl substituted with one methyl group, substituted phenyl substituted with two methyl groups and substituted phenyl substituted with one ethyl group; R2 is selected from the group consisting of substituted CH2 substituted with one or two methyl groups, ethane, and substituted ethane substituted with one or two methyl groups; R3 is selected from the group consisting of methyl and ethyl; and wherein n is 0 or l. These aryl ethers are especially useful in increasing the octane number of unleaded gasolines.
Abstract:
Vanadium-antimony catalysts have been found to be effective for the vapor phase condensation of saturated monocarboxylic acids or esters with formaldehyde, to produce unsaturated carboxylic acids or esters.
