2,2-Dimethyl-1,3-propanediol Usage And Synthesis
Chemical Propertieswhite solid
UsesNPG Glycol is used in the synthesis of tetraphenylporphyrins. Also used in the synthesis of Bryostatin 2, a protein kinase modulator.
UsesIn the manufacture of plasticizers, polyesters, as modifier of alkyd resins.
General DescriptionWhite crystalline solid. Melting point 130°C.
Air & Water ReactionsSoluble in water.
Reactivity Profile2,2-Dimethyl-1,3-propanediol may generate toxic gases in combination of with alkali metals, nitrides, and strong reducing agents. Reacts with inorganic acids and carboxylic acids to form esters plus water. Converted to aldehydes or acids by oxidizing agents. May initiate the polymerization of isocyanates and epoxides.
Health HazardMay be harmful by ingestion or skin absorption. Causes eye and skin irritation. Material is irritating to mucous membrane and upper respiratory tract. INHALATION: Call for medical aid. Remove to fresh air. If breathing has stopped, give artificial respiration. If breathing is difficult, give oxygen.
Fire HazardSpecial Hazards of Combustion Products: Emits toxic fumes under fire condition.
Purification MethodsCrystallise the diol from *benzene or acetone/water (1:1). [Beilstein 1 IV 2551.]
