Abstract: Acrylonitrile and methacrylonitrile are separated from mixtures, obtained by the ammonia oxidation of propylene or isobutylene, by extractive countercurrent methods wherein the extractive solvent is a 5- or 6-ring membered lactam, N-substituted lactam or lactone, an acyclic or cyclic sulphone or sulphoxide, an N-alkylcarboxylic amide, an N,N-dialkylcarboxylic acmide or propylene carbonate. The two phase flowing in counter current comprise the reaction mixture and the solvent and may be liquid/liquid phases or gas/liquid phases respectively. The process is illustrated by reference to flow drawings (not shown) representing a gas/liquid extraction and extractive distillation. A liquid/liquid extraction using an auxiliary solvent is also described. Examples relate to the use of N-methylpyrrolidone, propylene carbonate, 3 - methyltetramethylene sulphone, butyrolactone, dimethyl sulphoxide, N - q -hydroxyethyl pyrrolidone, and dimethyl-formamide as extractive solvents.

Abstract: Tricyclic nitrogenous compounds having strong plant growth regulating properties are disclosed. The compounds display the general formula wherein A is one of several nitrogen-containing radicals, R1, R2, R3 and R4 are selected from various recited aliphatic, aryl, araliphatic and heterocyclic groups. R3 and R4 may also together form one of a number of nitrogen, sulfur and oxygen containing radicals. These compounds have a variety of uses, including the reduction of plant growth height without harm to the plant.
