Abstract: Disclosed herein is a novel process for the preparation of 4-amino-3,5-pyridinedicarboxylate derivatives by (a) reaction of an acetonediester with a primary amine to form an enamine, (b) reaction with a carboxylic acid anhydride or halide to form a 2-alkylcarbonyl-3-amino-2-pentenedicarboxylate, and (c) reaction with a halogenated alkylnitrile to form the pyridinedicarboxylate product. The product is useful as a herbicide or an intermediate in the formation of a herbicide.

Abstract: Paving-grade asphalt compositions having improved resistance to weathering are described which are obtained by incorporating into a paving-grade asphalt either (1) the product obtained by alkylating phenol with a resin oil, i.e., a hydrocarbon fraction of medium molecular weight compounds in the C.sub.9 carbon range primarily aromatic in nature, or (2) the condensation product of formaldehyde with the alkylation product of phenol and a C.sub.4 raffinate stream consisting mainly of butene-1, butene-2 and isobutylene.

Abstract: Toluene and toluene derivatives are oxidatively dehydrocoupled to produce stilbene and stilbene derivatives by heating toluene or a toluene derivative in the vapor phase with a metal- and oxygen-containing composition which functions as an oxidant or oxygen carrier and has the empirical formulaSb.sub.a Pb.sub.b Bi.sub.c O.sub.dwherein a is 1, b is 0.2-10, c is 0-5 and d is a number taken to satisfy the average valences of the Sb, Pb and Bi in the oxidation states in which they exist in said composition. Alternatively, the same metal- and oxygen - containing composition can be employed as a catalyst for the dehydrocoupling reaction when oxygen or an oxygen-containing gas is heated with the hydrocarbon reactant.

Abstract: Oxidation and ammoxidation catalysts are disclosed which have the empirical formula Sb.sub.a V.sub.b Ti.sub.c O.sub.x, wherein a is at least 6, b is 1, and c is a number such that the ratio c/a is at least 0.5, and x is a number taken to satisfy the valence requirements of the Sb, V and Ti present in the catalyst. Such catalysts may be optionally supported on conventional supports, or may be unsupported.

Abstract: A combination of zinc oxide and zinc bromide employed as a catalyst for the reaction between phenol and a 1,2-dihaloethane wherein the halogen is chlorine, bromine or iodine provides for increased reaction rates as compared to the use of either zinc compound separately as catalyst and elimination of the induction period characteristic of the reaction when zinc oxide is used as the catalyst.

Abstract: The rate of reaction of ethylenically unsaturated compounds, carbon monoxide and water in the presence of catalyst systems consisting essentially of a rhodium or iridium compound and a halogen promoter to produce carboxylic acids is accelerated by including a minor amount of a compound of cobalt, iron or manganese in the reaction system.

Abstract: An improved process for the simultaneous and continuous production of acetic and propionic acids in a single reactor wherein the rate of propionic acid production is enhanced over that which prevails when this acid is produced separately in the same reactor under the same conditions, said rate enhancement being achieved by the introduction of methanol at a critical rate.
