1-Naphthyl isothiocyanate Chemical Properties,Usage,Production
Chemical Properties
white crystalline powder
General Description
Odorless white needles or powder. Tasteless.
Air & Water Reactions
1-Naphthyl isothiocyanate is moisture sensitive. . Undergoes slow hydrolysis. Insoluble in water.
Reactivity Profile
Isocyanates and thioisocyanates, such as 1-Naphthyl isothiocyanate, are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat. Acids and bases initiate polymerization reactions in these materials. Some isocyanates react with water to form amines and liberate carbon dioxide. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence, [Wischmeyer(1969)].
Fire Hazard
Flash point data for 1-Naphthyl isothiocyanate is not available, but 1-Naphthyl isothiocyanate is probably combustible.
Purification Methods
Crystallise the isothiocyanate from hexane (1g in 9 mL). It forms white needles and is soluble in most organic solvents but is insoluble in H2O. It is absorbed through the skin and may cause dermatitis. [Cymmerman-Craig et al. Org Synth Coll Vol IV 700 1963, Beilstein 12 H 1244, 12 III 2948.]
