TH33787B - Methods and evaporators for evaporation of oxidative-sensitive compounds. - Google Patents

Abstract

DC60 (18/05/52) Liquid, containing vaporizing oxidation-sensitive compounds, is evaporated in an evaporator where the liquid is brought in contact with a hot solid surface to form Evaporation by means of which direct contact must be avoided during the resulting vapor phase. and hot solid surfaces Don't matter and evaporator It consists of a heated solid surface, a preheating apparatus for heating solid surfaces, and a preheating apparatus for feeding liquids. which contains vaporizable compounds to the heated solid surface for which the liquid feeding pre-fabricated apparatus is designed. and established in the evaporator in such a way as to avoid direct contact between any phases. and the heated hard coat surface can be significant Liquids containing vapor-sensitive oxidation-sensitive compounds are evaporated in an evaporator. The liquid is brought in contact with the hot solid surface for evaporation by a process that must avoid contact with each other. exactly between the resulting vapor phase and the hot solid surface. and the evaporator consists of a heated solid surface. Finishing machines for heating solid surfaces and finishing machines for feeding liquids containing vaporized compounds to heated solid surfaces for which liquid feeding finishers are designed and installed. in the evaporator in such a way that exposure can be avoided. directly between the resulting vapor phase and the heated solid surface.
