摘要： Disclosed is a method of making a free-standing polyimide film. A solution is prepared of a polyamic acid 20 to 98 % imidized in an organic solvent and a coating of the solution is applied to a non-stick substrate. The coating is heated to a temperature high enough to evaporate all but 1 to 20 wt.% of the solvent and form a film. The film is removed from the substrate and is heated to evaporate the solvent to less than 1000 ppm.

摘要： The present invention provides an efficient process for the production of ethylene or a mixture of ethylene and vinyl chloride, in which some 1,2-dichloroethane (EDC) may also be produced, by reacting chlorine with ethane. The process is characterized by a conversion of ethane per pass through the reactor of at least about 50 %, and a combined molar yield of ethylene and vinyl chloride of at least about 80 % based on the ethane consumed. In accordance with this invention, there is provided a process for preparing ethylene or a mixture of ethylene and vinyl chloride by the reaction of ethane and chlorine which comprise: a) providing a stream of ethane feed gas and a stream of chlorine feed gas; b) preheating either said ethane stream only or both said ethane and chlorine streams; c) thoroughly mixing said ethane and chlorine feed gases within about one second and at a molar ratio of ethane to chlorine of at least about 0.9:1.0; d) said preheating being sufficient to enable the resultant mixture to have a temperature above the free radical formation temperature for chlorine; and e) permitting said ethane and chlorine in said mixture to react so that the reacted mixture has a temperature between about 600 DEG C and 800 DEG C; whereby the combined molar yield of ethylene and vinyl chloride is at least about 80 % of the ethane reacted.

摘要： Disclosed is a method and apparatus for reducing the formation of dioxins in flue gas from municipal solid waste incinerators and of removal hydrochloric acid from the flue gas. Optionally, the concentration of NOx can also be reduced and SOx can be removed by injecting ammonia through injection ports (17, 24, 29). Ammonia is injected into the flue gas in an amount at least sufficient to react stoichiometrically with the amount of hydrochloric acid present in the flue gas. If the control of NOx and SOx is also desired, then additional amounts of ammonia are injected with those gases and by use of a controller (38). Ammonium chloride and ammonium sulfite/sulfate precipitates from the flue gas when the temperature falls below about 180 DEG C, and can be collected on a moving grate (2).
