摘要:
Constant boiling, azeotrope-like mixtures of dichlorotrifluoroethane, 1,1-dichloro-1-fluoroethane and methanol and/or ethanol, the constant-boiling, azeotrope-like mixtures being useful in solvent cleaning applications.
摘要:
A stabilized azeotrope or azeotrope-like composition is disclosed with 1,1,2-trichloro-1,2,2-trifluoroethane and trans-1,2-dichloroethylene containing effective stabilizing amounts of lower alkoxyphenol, 1,2-butylene oxide, nitromethane and/or 1,2-propylene oxide.
摘要:
Azeotropic mixtures of 1,1-dichloro-1-fluoroethane (HCFC-141b) with methanol or ethanol, the azeotropic mixtures being useful in solvent cleaning applications.
摘要:
Es wird ein Verfahren angegeben, das der Dampfentfettung von Werkstücken dient und die bei derartigen Verfahren üblicherweise auftretenden Emissionen auf ein Minimum reduziert. Dies wird dadurch erreicht, daß die Eintauchgeschwindigkeit von Werkstücken und Werkstückträger in die Dampfzone so gewählt wird. daß die durch die Werkstücke und Werkstückträger verursachte Kühlleistung stets kleiner.. bleibt als die zur Verdampfung des Lösemittels aufgewendete Heizleistung. Dies wird am einfachsten dadurch erreicht, daß die Eintauchgeschwindigkeit so gewählt wird, daß das obere Dampfniveau 5 im wesentlichen konstant bleibt.
摘要:
To provide a novel detergent composition and an aerosol composition of same which, because they are nonflammable, possess little hazard of ignition or risk during fire, and which fall within the definition of nonhazardous materials under the Fire Prevention Law and do not require a hazardous material storage warehouse, and which are not subject to legal restrictions with respect to amounts that may be stored when the detergent composition is to be used in large quantities, and which moreover are of low toxicity, and which while having properties such that the environmental impact thereof in terms of depletion of the ozone layer and so forth is small, as well as washability and drying characteristics equivalent to those of conventional detergent compositions which are used as brake cleaner, and have very little tendency to attack rubber and/or resin, a detergent composition and an aerosol composition of same are made to contain (Z)-1-chloro-3,3,3-trifluoropropene and C 4 F 9 OCH 3 , C 3 F 7 OCH 3 , 1,1,2,2-tetrafluoro-1-(2,2,2-trifluoroethoxy)ethane, or other such HFE-type nonflammable fluorinated-type solvent.
摘要:
An azeotrope-like composition consisting essentially of 1,1,1,2,3-pentachloropropane and hydrogen fluoride is provided, as well as methods that involve such an azeotropelike composition.
摘要:
This invention relates to cleaning compositions comprising unsaturated fluorinated hydrocarbons. The invention further relates to use of said cleaning compositions in methods to clean, degrease, deflux, dewater, and deposit fluorolubricant. The invention further relates to novel unsaturated fluorinated hydrocarbons and their use as cleaning compositions and in the methods listed above.
