Abstract: A new substance which is useful as a plant growth regulator is 3-imino-2-(1-methyl-3-phenylthioureido)isoindolin-1-one, which may also exist in tautomeric form as 1-(2-cyanobenzoyl)-2-methyl-4-phenylthiosemicarbazide. Formative effects and increased fruit set are obtained by application of the growth regulator to crop plants.
Abstract: In the manufacture of an N-benzyl-N-isopropyl amide by reaction of N-benzyl-N-isopropylamine with an acid chloride, the amide product is obtained in better purity and yield by employing excess benzylisopropylamine as the acid accepting agent and recovering the amine for re-use by reacting the amine hydrochloride by-product with aqueous sodium hydroxide.

Abstract: Conversion of raw coal to distillate liquid and gaseous hydrocarbon products by solvent liquefaction in the presence of molecular hydrogen employing recycle of mineral residue is commonly performed at a higher thermal efficiency than conversion of coal to pipeline gas in a gasification process employing partial oxidation and methanation reactions. The prior art has disclosed a combination coal liquefaction-gasification plant employing recycle of mineral residue to the liquefaction zone wherein all the normally solid dissolved coal not converted to liquid or gaseous products in the liquefaction zone is passed to a gasification zone for conversion to hydrogen. In the prior art plant the amount of normally solid dissolved coal passed to the gasification zone is just sufficient to enable the gasification zone to produce the entire process hydrogen requirement.

Abstract: The products of the invention are vinyl end-capped oligomers which are prepared from 2,4-bis (p-aminobenzyl) aniline and a vinyl substituted aromatic monoamine, the principal component of which is the compound whose structure is shown in FIG. 3. The products are prepared from either of two (2) precursors. The first precursor is a compound whose structure is shown in FIG. 2 and which is prepared from 2,4-bis (p-aminobenzyl) aniline, a dianhydride of an aromatic tetracarboxylic acid such as 3,3'4,4'-benzophenonetetracarboxylic acid (BTDA) and a vinyl substituted aromatic monoamine, such as 3-aminophenyl-ethylene (APE). The second precursor is a complex amine salt having the structure shown in FIG. 6 and which is prepared from 2,4-bis-(p-aminobenzyl) aniline, a dialkyl ester of BTDA and APE.
