| 应用领域 | Uses: CIR ingredient: Methylene Chloride、Methylene chloride is predominantly used as a solvent in paint strippers and removers、as a process solvent in the manufacture of drugs、pharmaceuticals、and film coatings、as a metal cleaning and finishing solvent in electronics manufacturing、and as an agent in urethane foam blowing. It is used as an extraction solvent for spice oleoresins、hops、and for the removal of caffeine from coffee. However、due to concern over residual solvent、most decaffeinators no longer use methylene chloride.、Used as a paint stripper and an extraction solvent、[LaDou、p. 552] Also used as a blowing agent for polyurethane foam and a propellant for insecticides、[ATSDR Medical Management] No longer used as a fumigant in the U.S. [EPA Pesticides]、In US industries、the process use of methylene chloride ended in the mid-1990s、[PMID 24224613] Methylene chloride standard (29 CFR 1910.1052) requires medical surveillance if >action level >30 days、yr of >STEL >10 days、yr、Metal Degreasing [Category: Clean]、Painting (Solvents) [Category: Paint]、Leather Tanning and Processing [Category: Industry]、Sculpturing plastics [Category: Hobbies]、Woodworking [Category: Hobbies]、Lithography printing [Category: Hobbies]、Preparing and mounting animal skins (taxidermy) [Category: Hobbies]、For dichloromethane (USEPA、OPP Pesticide Code: 042004) there are 0 labels match.、SRP: Not registered for current use in the U.S.、but approved pesticide uses may change periodically and so federal、state and local authorities must be consulted for currently approved uses.、The active ingredient is no longer contained in any registered pesticide products ... "cancelled."、Postharvest fumigation of strawberries、commodity fumigation of grains、with ethylene for degreening citrus fruits.、The Food and Drug Administration (FDA) is amending its regulations to ban the use of methylene chloride as an ingredient of cosmetic products.、For more Uses (Complete) data for DICHLOROMETHANE (10 total)、please visit the HSDB record page.、Methylene chloride is widely used as a solvent in industrial processes、paint stripper、and degreaser. It is also used in food preparation、aerosol propellants、pesticides、and the manufacture of photographic film. (T10、L188)、Use Classification: Chemical Classes -> Pesticides (chemicals used for killing pests、such as rodents、insects、or plants)、Food Additives -> EXTRACTION_SOLVENT -> JECFA Functional Classes、Cosmetics -> Solvent、Industry Uses: Solvent、Other、Processing aids not otherwise specified、Fuel、Cleaning agent、Waterproofing agent、Not Known or Reasonably Ascertainable、Refrigerants、Intermediate、Adhesion、cohesion promoter、Laboratory chemicals、Consumer Uses: Not Known or Reasonably Ascertainable、Solvent、Household Products: Cosmetics product ingredient: Methylene chloride (Dichloromethane)、Source: Dichloromethane is a sweet smelling volatile liquid used to dissolve other ingredients. Dichloromethane may be used in aerosol cosmetics (such as hairspray) to help the product spray out of the can. Dichloromethane may also be used in aerosol foams (such as mousse) to help make the product foamy.、Potential health impacts: The main routes of exposure to dichloromethane are inhalation or skin contact. Acute exposure of humans to dichloromethane can cause optic nerve damage and liver inflammation. Prolonged skin contact with dichloromethane can cause skin irritation or chemical burns. Studies of mice that inhaled dichloromethane found an increase in liver and lung tumors. The International Agency for Research on Cancer (IARC) considers dichloromethane to be possibly carcinogenic to humans. California Proposition 65 lists dichloromethane as a carcinogen.、Product count: 55、Information on 84 consumer products that contain Methylene chloride in the following categories is provided:、• Auto Products、• Commercial、Institutional、• Home Maintenance、• Inside the Home、• Pesticides、Methods of Manufacturing: The predominant method of manufacturing methylene chloride employs as a first step the reaction of hydrogen chloride and methanol to give methyl chloride. Excess methyl chloride is then mixed with chlorine and reacts to give methylene chloride、chloroform、and carbon tetrachloride as coproducts. This reaction is usually carried out in the gas phase thermally but can also be done catalytically or photolytically. Parallel reactor trains operating on different feeds、CH4-CH3Cl or CH3Cl-CH2Cl2、are known. At low temperature and high pressure、the liquid-phase process is capable of giving high selectivities to methylene chloride.、...、A、lesser used method involves a direct reaction of excess methane with chlorine at high temperatures、approximately 400-500 °C、or at somewhat lower temperatures either catalytically or photolytically. This process produces methyl chloride、and carbon tetrachloride as coproducts. The temperature and raw material flow rates to the reactor can be controlled to maximize the production of the particular chloromethane desired. The reactor effluent also contains unreacted methane and hydrogen chloride. Methane is recovered by removing the HCl by water washing and then drying before recycling. The liquid chloromethane stream、which contains the methylene chloride and its coproducts、passes through a sequence of fractionating columns after washing、alkali scrubbing、and drying.、Formulations、Preparations: Premix Partners: Methyl eugenol、naled.、Dichloromethane is available as commercial、technical grade & grades intended specifically for vapor degreasing、aerosol use、food extraction、reagent use & spectrophotometry.
