Abstract: Disclosed is an improved process for the continuous production of aromatic carboxylic acids by the liquid-phase oxidation of an alkyl aromatic compound with an oxygen-containing gas in the presence of oxidation catalyst which effectively utilizes the heat of reaction in the process of removing excess water generated from the reaction and minimizes the loss of solvent used as the carrier for the reaction catalyst. Operation of the process is improved by removing reactor off-gas directly into a water removal column for distillation. A portion of distillate condensed from the overhead aqueous vapors of the water removal column is refluxed to the fractionating zone of the water removal column. A bottoms liquid of partially de-watered process solvent obtained from the water removal column is sprayed into the reactor above the phase separation of the gas/liquid contents thereby enriching the water content of the reactor off-gas to improve the efficiency of the water removal column without additional heat input beyond that of the heat of reaction.

Abstract: A process for the production of elastomeric polypropylene is disclosed. The process entails contacting the propylene monomer neat or in an unreactive hydrocarbon solvent, with a catalyst in a recirculated, stirred reactor at a temperature of 60 to 80 DEG C thereby producing elastomeric polypropylene. The reactor contents are in the slurry/solution phase and are essentially free of catalyst poisons. The reactor is capable of recirculating contents that are very viscous such that the reactor contents are well mixed while a portion of the contents of the reactor containing propylene, any solvent, and elastomeric polypropylene are continually removed by the use of a high viscosity pump to recover the elastomeric polypropylene.

Abstract: Disclosed is an improved process for the preparation of tocopherol and tocopherol/tocotrienol concentrates from vegetable oil distillates. Tocopherol concentrates are obtained containing 20-80 % tocopherol by weight, with an overall recovery of tocopherol of 72 % to 97 %. The process is comprised first of an esterification reaction where the more volatile alcohols are converted to their less volatile fatty acid esters, followed by a series of distillation steps where components boiling higher and lower than the tocopherols are separated from tocopherols and other like boiling substances. Advantages of the process are that tocopherol and tocopherol/tocotrienol concentrates are produced efficiently and economically in a minimum number of steps without the use of solvents and with a relatively small capital investment.
