| 应用领域 | Uses: Isophorone is used mainly as a solvent for concentrated vinyl chloride、acetate-based coating systems for metal cans、other metal paints、nitrocellulose finishes、and printing inks for plastics. Isophorone is an intermediate in the synthesis of 3、5-xylenol、3、5-trimethylcyclohexanol、and plant growth retardants.、Used as a solvent for coatings、especially vinyl resins applied by roller、also used as a chemical intermediate and a solvent for other materials、[ACGIH]、Painting (Solvents) [Category: Paint]、For Isophorone (USEPA、OPP Pesticide Code: 047401) 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.、SOLVENT FOR LACQUERS & PLASTICS、SOLVENT FOR MANY OILS、FATS、GUMS、RESINS、NITROCELLULOSE、& VINYL-RESIN COPOLYMERS、CHEM INT FOR 3、5-TRIMETHYLCYCLOHEXANOL、& 3、5-XYLENOL、SPECIALTY SOLVENT、For more Uses (Complete) data for ISOPHORONE (9 total)、please visit the HSDB record page.、Use Classification: Flavouring Agent -> FLAVOURING_AGENT -> JECFA Functional Classes、Flavoring Agents -> JECFA Flavorings Index、Flavouring Agent -> FLAVOURING_AGENT -> JECFA Functional Classes、Industry Uses: Other、Solvent、Adhesion、cohesion promoter、Intermediate、Stabilizing agent、Not Known or Reasonably Ascertainable、Consumer Uses: Not Known or Reasonably Ascertainable、Methods of Manufacturing: ACETONE ... IS PASSED OVER CALCIUM OXIDE、HYDROXIDE OR CARBIDE OR THEIR MIXT AT 350 °C AND ATMOSPHERIC PRESSURE、OR IT IS HEATED @ 200-250 °C UNDER PRESSURE. ISOPHORONE IS SEPARATED FROM RESULTANT PRODUCTS BY DISTILLATION.、Produced by the condensation of acetone in the liquid phase at ca. 200 °C and 3.6 Mpa in the presence of an aqueous potassium hydroxide solution (ca. 1%). The process steps condensation、separation of unreacted acetone、and hydrolysis of byproducts can be carried out in a single reactor. Reaction in the gas phase at 350 °C over calcium-aluminum oxide has also been reported.、Review of preparation and purification: G.S. Salvapati、M. Janardanarao、J. Sci. Ind.
