应用领域Uses: Used to make pharmaceuticals、photographic and photothermographic chemicals、dyes、pigments、agricultural chemicals、and rubber、Also used in epoxy resin systems for semiconductor potting compounds and soldering masks、as dyeing auxiliary for acrylic fibers and plastic foams、and in polymers such as epoxy resin pastes and acrylic rubber-fluororubber、[HSDB] Present in caramel coloring、tobacco smoke、wine、soy sauce、and other foods、Also formed when ammonia is added to livestock feed to increase nutritional value、Used in various polymers including acrylic rubber-fluororubber laminates、films、adhesives、textile finishes、and epoxy silane coatings、[NTP]、Semiconductor Manufacturing [Category: Industry]、Working with Glues and Adhesives [Category: Other]、Plastic Composites Manufacturing [Category: Industry]、Textiles (Printing、Dyeing、or Finishing) [Category: Industry]、Dyeing auxiliary for acrylic fibers、plastic foams、Used in the manufacture of pharmaceuticals、agricultural chemicals and rubber、Used in epoxy resin systems for semiconductor potting compounds and soldering masks、Component of polymers including epoxy resin pastes、acrylic rubber-fluororubber、Industry Uses: Hardener、Intermediate、Catalyst、Not Known or Reasonably Ascertainable、Consumer Uses: Hardener、Methods of Manufacturing: In the generally applicable Radziszewski reaction、a 1、2-dicarbonyl compound is condensed with an aldehyde and ammonia (R1 = H) in a molar ratio of 1:1:2、respectively. Replacement of a molar equivalent of ammonia with a primary amine (R1 = alkyl or aryl) leads to the corresponding 1-substituted imidazoles. The reaction is usually carried out in water or a water-alcohol mixture at 50 - 100 °C. Work-up may involve the usual processes (e.g.、distillation、extraction、and crystallization). Distillation leads to imidazole with a purity > 99%. The yield is generally 60 - 85 %. ...
