| 应用领域 | Uses: Used as an acrylic fiber comonomer、grafting reagent (ashless lubricant dispersants)、and chemical intermediate、[HSDB]、Acrylic fiber comonomer、Used as a chemical intermediate for the synthesis of: 2-ethylpyridine、vinylpyridine copolymers、latex、2-Vinylpyridine is a large-volume specialty chemical used primarily for manufacturing terpolymers、e.g.、styrene、butadiene、and vinylpyridine、used to coat fabric cords of tires and fabric-reinforced rubber products、such as belts.、Industry Uses: Intermediate、Methods of Manufacturing: Alpha-picoline + formaldehyde (condensation、dehydration)、...manufactured by treatment of 2-methylpyridine with aqueous formaldehyde、followed by dehydration of the resulting intermediate alcohol. The reaction is carried out at 150 to 200 °C in an autoclave. After removal of unreacted 2-methylpyridine by distillation、concentrated aqueous sodium hydroxide is added to the residue and the resultant mixture is distilled under reduced pressure. During distillation、the dehydration of 2-(2-pyridyl)ethanol occurs to give 2-vinylpyridine as a distillate、which can be purified further by fractional distillation under reduced pressure in the presence of an inhibitor such as 4-tert-butylcatecohol.、Formulations、Preparations: COMMERCIAL 2-VINYLPYRIDINE ... SUPPLIED WITH SMALL AMT OF POLYMERIZATION INHIBITORS ADDED.、Consumption Patterns: ESSENTIALLY 100% AS MONOMER、U.S. Production: 2023: 1、000、000 - <5、000 lb、2022: 1、2021: 5、000 - <10、2020: 5、(1972) PROBABLY GREATER THAN 4.54X10+5 GRAMS、(1975) 2.0X10+9 GRAMS (CONSUMED IN TERPOLYMER)、...demand is as much as 3000 t annually、General Manufacturing Information: Synthetic Rubber Manufacturing、Pyridine、2-ethenyl-: ACTIVE、... been investigated for use in synthetic rubbers、photographic film、ion exchange resins、and other polymers as well as pharmaceuticals. |
