| 应用领域 | Uses: Used to make dyes、pigments、fungicides、insecticides、pharmaceuticals、and perfumes、Also used as antioxidants for rubber、fats、and oils、as an antiseptic、for lubrication of steam turbines、electric motors、hydraulic equipment、and instruments、and formerly as an anthelmintic、[HSDB] Also used as an additive in electroplating、developer in dyeing and printing of fabrics、in tanneries、and in the paints-lacquers-varnishes industry、[IUCLID]、Electroplating [Category: Plate]、Painting (Pigments、Binders、and Biocides) [Category: Paint]、Using Disinfectants or Biocides [Category: Clean]、Leather Tanning and Processing [Category: Industry]、Textiles (Printing、Dyeing、or Finishing) [Category: Industry]、MEDICATION、For 2-naphthol (USEPA、OPP Pesticide Code: 010301) 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 principal uses for 2-naphthalenol are in the dyes and pigments industries、eg、as a coupling component for azo dyes、and to make important intermediates、such as 3-hydroxy-2-naphthalenecarboxylic acid (BON) and its anilide (naphthol AS)、2-naphtholsulfonic acids、aminonaphtholsulfonic acids、and 1-nitroso-2-naphthol.、Antioxidants for ... fats、oils、synthesis of fungicides、... antiseptic.、For more Uses (Complete) data for 2-NAPHTHOL (8 total)、please visit the HSDB record page.、This is a man-made compound that is used as a pesticide.、Industry Uses: Pigment、Intermediate、Dye、Consumer Uses: Pigment、Methods of Manufacturing: 2-Naphthol is produced by caustic fusion of naphthalene-2-sulfonic acid. Typically、the sodium salt of the sulfonic acid is added gradually to 50% sodium hydroxide liquor at 300 °C、the melt is then heated further at 320 °C in a gas-fired iron vessel with vigorous agitation. After completion of the reaction、the melt is run into excess water、possibly including filtrate from the previous batch at a proven tolerable level、and the naphtholate solution is neutralized to pH 8 with dilute sulfuric acid. If the temperature is maintained at >100 °C during neutralization、the crude product comes out of solution as an oil、which is separated、washed with hot water、and distilled under vacuum to give pure 2-naphthol. The molten material is processed through a flaker to give the final product for packaging. The fusion yield is about 80% of the theoretical value、resulting in an overall yield of 70% based on naphthalene.、... Alkylation and isomerization are carried out up to 240 °C with a phosphoric acid catalyst. Final catalytic oxidation at 90 - 110 °C gives the hydroperoxide、which is cleaved with dilute sulfuric acid to give 2-naphthol in high overall yield in spite of modest oxidation conversion.、By fusing sodium beta-naphthalene sulfonate with caustic soda. Product is distilled in vacuo and then sublimed.、Formulations、Preparations: Grade: Technical、sublimed、resublimed、U.S. Production: 2023: 1、000、000 - <5、000 lb、2022: 1、2021: 1、2020: 1、2-Naphthalenol is listed as a High Production Volume (HPV) chemical (65FR81686). Chemicals listed as HPV were produced in or imported into the U.S. in >1 million pounds in 1990 and、or 1994. The HPV list is based on the 1990 Inventory Update Rule. (IUR) (40 CFR part 710 subpart B、51FR21438).、Production volume for non-confidential chemicals reported under the 2006 Inventory Update Rule. Chemical: 2-Naphthalenol. Aggregated National Production Volume: 1 to < 10 million pounds.、Non-confidential 2012 Chemical Data Reporting (CDR) information on the production and use of chemicals manufactured or imported into the United States. Chemical: 2-Naphthalenol. National Production Volume: 1、000 - 10、yr.、General Manufacturing Information: Synthetic Dye and Pigment Manufacturing、2-Naphthalenol: ACTIVE |
