登记用途：Uses: CIR ingredient: n-Butyl Alcohol、Used as a solvent and chemical intermediate、[ACGIH]、Semiconductor Manufacturing [Category: Industry]、Painting (Solvents) [Category: Paint]、... is employed as a solvent for paints、lacquers & varnishes、natural & synthetic resins、gums、vegetable oils、dyes & alkaloids. It is used as an intermediate in the manufacture of pharmaceuticals & chemicals、& employed in industries producing artificial leather、textiles、safety glass、rubber cement、shellac、raincoats、photographic films & perfumes.、BA is used primarily as an industrial intermediate in the production of ethers and butyl ether acetates、pharmaceuticals、polymers and plastics. BA is used to a lesser extent as a solvent、reactant、diluent and component in consumer (nail polish formulations、rubber cement and safety glass) and industrial products.、As organic solvent for fats、waxes、resins、varnish gums、etc.、manufacture lacquers、rayon、detergents、other butyl compounds、in microscopy for preparing paraffin imbedding materials.、n-Butyl Alcohol is a primary aliphatic alcohol historically used as a solvent in nail care cosmetic products、but new concentration of use data indicate that it also is being used at low concentrations in eye makeup、personal hygiene、and shaving cosmetic products. n-Butyl Alcohol has been generally recognized as safe for use as a flavoring substance in food and appears on the 1982 Food and Drug Administration (FDA) list of inactive ingredients for approved prescription drug products...、For more Uses (Complete) data for N-BUTYL ALCOHOL (9 total)、please visit the HSDB record page.、Use Classification: Fragrance Ingredients、Flavouring Agent -> FLAVOURING_AGENTFood Additives -> EXTRACTION_SOLVENT -> JECFA Functional Classes、Flavoring Agents -> JECFA Flavorings Index、Cosmetics -> Denaturant、Solvent、SOLVENTS、Industry Uses: Plasticizers、Flotation agent、Intermediate、Adhesion、cohesion promoter、Paint additives and coating additives not described by other categories、Defoamer、Cleaning agent、Plasticizer、Catalyst、Diluent、Not Known or Reasonably Ascertainable、Stabilizing agent、Surfactant (surface active agent)、Chemical reaction regulator、Flavoring and nutrient、Solvents (which become part of product formulation or mixture)、Conductive agent、Dispersing agent、Other、Consumer Uses: Dispersing agent、Fuel、Household Products: Information on 77 consumer products that contain Butanol in the following categories is provided:、• Auto Products、• Hobby、Craft、• Home Maintenance、• Inside the Home、• Landscaping、Yard、• Personal Care、• Pesticides、Methods of Manufacturing: The principal commercial source of 1-butanol is n-butyraldehyde、obtained from the Oxo reaction of propylene. A mixture of n- and isobutyraldehyde is obtained in this process、this mixture is either separated initially and the individual aldehyde isomers hydrogenated、or the mixture of isomeric aldehydes is hydrogenated directly and the n- and isobutyl alcohol product mix separated by distillation.、n-Butyl alcohol is obtained by fermentation of glycerol、mannite、starches、and sugars in general、using Bacillus butylicus sometimes synergized by presence of Clostridium acetobutyricum、synthetically、from acetylene.、Manufacture from ethylene oxide and triethylaluminum、... by oxidation of tributylborane. ... Manufacture by carbohydrate fermentation、by hydrogenation of butyraldehyde、from crotonaldehyde.、Ethyl alcohol may be converted directly to 1-butanol at 325 °C and 13 MPa (128 atm) over magnesium oxide、copper oxide. A mixture of butanol、hexyl and octyl alcohols、acetaldehyde、butyraldehyde、and crontonaldehyde is obtained when ethanol and hydrogen are passed over magnesium oxide at 200 °C and 10 MPa (99 atm). Butyl bromide can be hydrolyzed at 130-180 °C at 350-700 kPa (3.5-6.9 atm) to give a mixture of butanol and dibutyl ether、the dibutyl ether can be converted to 81% butanol by heating with 48% aq hydrobromic acid in an autoclave at 150 °C. An 82% yield of 1-butanol can be obtained from a low temp reduction of n-butyraldehyde with sodium borohydride. At 200-300 °C and 10 MPa (99 atm)、furan has been reduced in the presence of copper chromite-barium chromite catalyst to butanol in 70% yields.、For more Methods of Manufacturing (Complete) data for N-BUTYL ALCOHOL (7 total)、Formulations、Preparations: GRADE OR PURITY: 99+%、Consumption Patterns: 20% AS A SOLVENT FOR SURFACE COATINGS、14% FOR SYNTHESIS OF GLYCOL ETHERS (INCL ETHYLENE GLYCOL MONOBUTYL ETHER)、12% FOR PLASTICIZERS (INCL DIBUTYL PHTHALATE)、20% FOR N-BUTYL ACETATE、10% EXPORTED、7% FOR SYNTHESIS OF N-BUTYL ACRYLATE、15% FOR MISC APPLCNS (INCL SYNTHESIS OF BUTYLAMINES AND 2、4-D ESTERS) (1972)、30% FOR BUTYL ACRYLATES AND METHACRYLATE、23% FOR GLYCOL ETHERS、12.5% FOR BUTYL ACETATE、12.5% FOR SOLVENT、8% FOR PLASTICIZERS、5% FOR AMINO RESINS、1% FOR AMINES、1% MISCELLANEOUS、7% FOR EXPORTS (1984)、CHEMICAL PROFILE: n-Butanol.
