The preferred embodiment is the enantiomer cis-(1S)-N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalenam ine and its pharmaceutically acceptable acid addition salts.

Abstract: The heat provided to a cracking furnace is manipulated so as to maintain the actual conversion of a first component in the feed stream flowing to the cracking furnace substantially equal to the desired conversion for the first component. The actual conversion of the first component is determined based on an analysis for the concentration of the first component in the feed stream flowing to the cracking furnace, an analysis of the concentration of the first component in the product stream flowing from the cracking furnace, an estimate of the conversion of the first component and a calculation of the expansion of the feed stream in the cracking furnace. The thus derived actual conversion is compared to a desired conversion with the results of the comparison being utilized in combination with the feed flow rate to manipulate the heat provided to the cracking furnace.

Abstract: Disclosed herein is a process of synthesizing urea including reacting ammonia and carbon dioxide at a urea synthesis pressure and temperature in a urea synthesis zone, separating excess ammonia and unreacted ammonium carbamate from the thus-obtained urea synthesis melt as a gaseous mixture containing ammonia and carbon dioxide, recirculating the gaseous mixture to the urea synthesis zone, and, on the other hand, obtaining urea from an aqueous urea solution which has been obtained by separating the excess ammonia and unreacted ammonium carbamate. The above process features ingeniously combined conditions of various process steps. It produces urea using less high-pressure steam and recovers less low-pressure steam. A stripping operation making use of carbon dioxide can be effectively incorporated in the above process. The above process permits to cut the construction cost of a urea synthesis plant.

Abstract: A one-step process for the preparation of N-substituted (meth)acrylamides from the reaction of a (meth)acrylate ester and an amine over a catalytic amount of a metal alkoxide catalyst is described. These catalysts, such as stannous dimethoxide, lead dimethoxide, zinc dimethoxide, copper dimethoxide and bismuth tributoxide give high selectivity to the N-substituted (meth)acrylamides and little selectivity of the Michael adduct propionate ester, which would predominate in the absence of these catalysts. Also, these catalysts are less costly than organo metal catalysts commonly used.

Abstract: Ethylidene bisformamide is prepared by reacting, at elevated temperatures, dry acetaldehyde and formamide in the presence of an acidic catalyst and an ammonia scavenger such as acetic anhydride. The bisformamide is recovered as a bottoms products of high speed low residence time distillation techniques, e.g., wiped film evaporation. The resulting ethylidene bisformamide may be cracked to N-vinylformamide, which monomer is useful in the preparation of active polymers and copolymers, including poly(vinylformamide) which can be hydrolyzed to poly(vinylamine) salts by contact with acid. These amine salts can then be converted to the free amines, which are precursors of polymeric dyes and pharmaceuticals.
