butanethiol usage and synthesis |
chemical properties |
colourless liquid |
general description |
a clear, colorless liquid with a strong skunk-like odor. flash point in range -18 to 43°f. less dense than water and slightly soluble in water. vapors heavier than air. |
air & water reactions |
highly flammable. slightly soluble in water. |
reactivity profile |
butanethiol is incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. reactions with these materials generate heat and in many cases hydrogen gas. may liberate hydrogen sulfide upon decomposition or reaction with an acid. incompatible with strong oxidizing agents [uscg, 1999]. |
health hazard |
inhalation causes loss of sense of smell; muscular weakness. convulsions, and respiratory paralysis may follow prolonged exposure. contact of liquid with eyes or skin causes slight irritation. ingestion causes nausea. |
