Abstract:
A process for producing dialkoxyalkanes by reacting a dihaloalkane with an aliphatic alcohol in the presence of at least one metal or metallic compound selected from the group consisting of metals and metallic compounds of Groups I-V and transition metals of Groups VI-VIII of the Periodic Table.
Abstract:
The present invention relates to a process for the production of modified polypropylenes having a good adhesiveness to inorganic fibers and metals. The process is characterized by heating crystalline polypropylene and one or more of alicyclic carboxylic acids having a cis form double bond in the ring and their anhydrides in the presence of a radical producing agent.
Abstract:
A METHOD FOR RECOVERING A REACTION CATALYST FROM AN OXO OR AN ALDOX PROCESS IN WHICH THE WASTE CATALYSTCONTAINING SOLUTION OBTAINED BY THE DECATALYXING STEP IS TREATED WITH AN ORGANIC EXTRACTING MEDIUM AND AN ALKALI METAL HYDROXIDE IN ORDER TO OBTAIN THE CATALYST METAL OR METALS IN THE FORM OF HYDROXIDES SUSPENDED IN THE ORGANIC EXTRACTING MEDIUM.
Abstract:
A synthetic lubricating oil composition which is suitable for lubrication of mechanical super charger, which composition comprises (A) a diester of an aliphatic dibasic acid having 4 to 14 carbon atoms and an alcohol having 4 to 14 carbon atoms, or a mixture thereof, of which viscosity at 100 DEG C. is 2-7 mm2/s; and (B) a polyoxyalkylene glycol ether or a polyoxyalkylene glycol ester having 2 to 5 carbon atoms in its alkylene group, or a mixture thereof, of which viscosity at 100 DEG C. is not less than 30 mm2/s; and which composition may further comprise (C) an alpha -olefin oligomer having a kinematic viscosity at 100 DEG C. of 3-6 mm2/s.
Abstract:
The invention relates to a hydrocarbon conversion catalyst and process for making same. The catalyst comprises a refractory oxide as a carrier, between about 0.01 and 6% by weight of a Group VIII metal, between about 0.01 and 6% by weight of cadmium, between about 0.01 and 6%, by weight of tin and between about 0.1 and 5% by weight of a halogen (each per cent being based on the total catalyst). The catalyst has particular applicability to reforming processes.
Abstract:
1. A PROCESS FOR THE CONVERSION OF A HEAVY HYDROCARBON OIL COMPRISING CONTACTING SAID OIL WITH HYDROGEN AND A CATALYST COMPOSITE COMPRISING A CATALYTIC METAL OR COMPOUND THEREOF ON A POROUS SILICA-ALUMINA CARRIER HAVING A SILICA CONTENT IN THE RANGE OF BETWEEN 0 AND ABOUT 30% BY WEIGHT AND FURTHER CHARACTERIZED IN THAT: (1) THE VOLUME OF THE PORES IN SAID CATALYST HAVING A RADIUS IN THE RANGE OF FROM ABOUT 0 TO ABOUT 3000 A. IS GREATER THAN ABOUT 0.30 ML./G.; (2) THE VOLUME OF THE PORES IN SAID CATALYST HAVING A RADIUS IN THE RANGE OF FROM ABOUT 0 TO ABOUT 30 A. IS LESS THAN ABOUT 25% OF THE VOLUME OF THE PORES HAVING A RADIUS IN THE RANGE OF FROM ABOUT 0 TO ABOUT 300 A.; (3) THE VOLUME OF THE PORES HAVING A RADIUS IN THE RANGE OF FROM ABOUT 75 TO ABOUT 3300 A. IS LESS THAN ABOUT 40% OF THE VOLUME OF THE PORES HAVING A RADIUS IN THE RANGE OF FROM ABOUT 0 TO ABOUT 300 A.; AND (4) THE VOLUME OF THE PORES HAVING A RADIUS IN THE RANGE OF FROM ABOUT 75 TO ABOUT 75,000 A. IS SMALLER THAN ABOUT 0.25 ML./G.
Abstract:
The invention relates to (1) the preparation of a catalyst comprising cobalt carbonyl in admixture with a metal substance selected from the group consisting of a metal of Groups I or II of the Periodic Table, useful as an oxo reaction catalyst by reacting the corresponding free metals or a compound thereof in a liquid medium with carbon monoxide and hydrogen in the presence of palladium, platinum or gold; (2) regenerating spent cobalt catalysts of the foregoing type by applying the same reagents and conditions to the spent catalyst.
