Abstract
The invention discloses a stabilizer for trichloroethylene. The stabilizer consists of an organic base, an antioxidant and an organic solvent, wherein the organic base is triethanolamine; the antioxidant is 2-isopropane, thymol and epichlorohydrin; and the organic solvent is isobutanol and diethylene glycol. The stabilizer disclosed by the invention has the following advantages: the composite stabilizer formulation is used for stabilizing trichloroethylene and ensuring that trichloroethylene does not deteriorate within 180 days, and simultaneously, the decomposition speed of trichloroethylene in a use process is reduced, and the use time is greatly prolonged. By utilizing the stabilizer, trichloroethylene can meet the requirement of the top-grade electronic cleaning industry on trichloroethylene quality, cannot damage and erode cleaned components and achieves the purpose of replacing imported trichloroethylene.
Description
Technical field
The present invention relates to a kind of stablizer of trieline, be applicable to the long storage of trieline, particularly the long storage of electronics wash stage trieline.
Background technology
Trieline, colourless transparent liquid has the taste of chloroform.Fusing point :-87.1 ℃, boiling point: 87.1 ℃, relative density (water=1): 1.46, relative vapour density (air=1): 4.53.Meet naked light, high heat energy causes combustion explosion, contact with strong oxidizer chemical reaction can occur, chance illumination or with water, can decompose when air exists generates poisonous phosgene and corrosive hydrogenchloride.Water insoluble, be dissolved in ethanol, ether, can be miscible in toluene, the most organic solvents of acetone.
Trieline is the strongest a kind of of solvency power in the C2 chlorinated solvents, it is best metal degreasing lotion, be mainly used in the industries such as colour TV, refrigerator, automobile, air-conditioning, precision optical machinery, microelectronics and make the clean-out system of metal parts, electronic component, its major advantage is that degreasing is thorough.Be used on the industrial chemicals and can produce the products such as Mono Chloro Acetic Acid, dichloroacetyl chloride, Octachlorodipropyl Ether, hexachloroethane, can also be used as solvent and extraction agent, at agricultural chemicals and pharmaceutical industries certain purposes is arranged also.Trieline also can be used for the substitute of production Chlorofluorocarbons (CFCs): HFC-134a, HFC-100, HCFC-123, HCFC-124, HCFC-125, and replaces most of purposes of 1.1.1-TCA.
Because the labile characteristic of trieline, the trieline decomposition generates corrosive hydrogenchloride after use for some time, can produce the equipment that cleans to corrode, and it is healthy that the obnoxious flavoures such as phosgene that simultaneously decomposition produces also damage personnel.
Domestic stablizer for the trieline normally organic bases of single interpolation improves the material pH value, but can only keep 30 days left and right sides time, with Foreign Advanced Lerel larger gap is arranged, simultaneously, some high-grade electronics cleaning industry to the quality of trieline and add stablizer special requirement arranged, can not produce to the element that is cleaned the damage corrosion.
Summary of the invention
