| 应用领域 | Uses: CIR ingredient: 1、5-Pentanediol、Used as plasticizer and brake fluid additive、Also used to make polyesters for emulsifying agents and resin intermediates、[Merck Index]、For 1、5-pentanediol (USEPA、OPP Pesticide Code: 690202) 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.、1、5-Pentanediol is used as a building block in the production of polyesters、thermoplastic polyurethanes、and plasticizers. The linear structure with an uneven number of carbon atoms gives rise to a relatively low viscosity and glass transition temperature (Tg) and good flexibility. 1、5-Pentanediol is also used as an intermediate for dyes and of pharmaceuticals and pesticides. It can be used、for example、for the production of various heterocyclic compounds、such as 1-methylpiperidine.、As a plasticizer in cellulose products and adhesives、in brake fluid compositions. Forms esters and polyesters which can be used as plasticizers、emulsifying agents and resin intermediates.、MEDICATION、5-Pentanediol has been reported to have antimicrobial and antifungal properties in pharmaceutical applications. Additionally、5-Pentanediol has reported uses in products for hair loss、cold sores、nail problems、dry and scaly feet、and eczema、it can be used as a moisturizing substance and solvent.、Industry Uses: Solvent、Intermediate、Consumer Uses: Diluent、Household Products: Information on 19 consumer products that contain 1、5-Pentanediol in the following categories is provided:、• Home Office、• Inside the Home、• Personal Care、Methods of Manufacturing: 1、5-Pentanediol usually is produced by catalytic hydrogenation of glutaric acid or of its esters、e.g.、dimethyl glutarate、although dicarboxylic acid mixtures containing glutaric acid also may be used、giving typically a mixture of 1、4-butanediol、5-pentanediol、and 1、6-hexanediol.、Prepd by hydrogenolysis of tetrahydrofurfuryl alcohol in the presence of copper chromite.、Impurities: A gas chromatographic、mass-spectrometry analysis was performed to determine the impurities in 1、5-Pentanediol. 1、5-Pentanediol was found to be 98.1% pure with a total of 0.28% unknown impurities、stated by the authors not to be diols. Contamination by water、5-hexanediol、6-Hexanediol was found to be 0.02%、1.02%、and 0.56%、respectively. Other diol impurities、including 1、4-Butanediol、2、5-Hexanediol、and cyclic diols、were below the limit of detection (< 0.05%).、Formulations、Preparations: Grade: Technical、U.S. Production: 2023: 2、500、000 - <4、000、000 lb、2022: 4、000 - <5、2021: 4、2020: 2、Non-confidential 2012 Chemical Data Reporting (CDR) information on the production and use of chemicals manufactured or imported into the United States.
