Disulfide ethyl alcohol

Gas repulsive odor. d4J 0.686, mp —132.5°. hp — 14.5°. Dec 300°. Ignites spontaneously in air- Slowly dec in water. Explodes on contact with sulfur hexaflnoride reacts vigorously with carbon tetrachloride and chloroform. Sol in carbon disulfide, ethyl alcohol, benzene, and ethyl silicate. Potassium hydroxide liberates hydrogen.

The Italian chemical journal, Rassegna Chemica 50), contains articles on technical and industrial developments and on chemical markets in Italy. Monthly statistics on Italian chemical production (quoted from the Ministry of Industry and Commerce) include the following synthetic ammonia, nitric acid, sulfuric acid, sodium carbonate, caustic soda, alumina, trichlorethylene, calcium carbide, carbon disulfide, explosives, superphosphates, ammonium sulfate, calcium cyanamide, calcium nitrate, ammonium nitrate, copper sulfate, dyestuffs, ethyl alcohol, methanol, tanning extracts, tartaric acid, citric acid, wood pulp and cellulose, and sodium nitrate. 

The combined effect of carbon disulfide exposure and ethyl alcohol has been examined to determine if carbon disulfide exposure results in the Antabuse syndrome, an intolerance to alcohol. The metabolism of Antabuse, disulfuram, or tetraethylthiuram disulfide (TETD) produces carbon disulfide and diethylamine. The metabolites of Antabuse inhibit the enzymes necessary to metabolize ethyl alcohol (aldehyde dehydrogenase and catalase), which results in the Antabuse syndrome due to a buildup of aldehyde. Symptoms include a sensation of heat, a fall in blood pressure, nausea, and in extreme cases circulatory collapse (Djuric 1971). Research by Freundt et al. (1976) on rats and humans of the combined effects of carbon disulfide exposure and ethanol ingestion indicate that, at low (20 ppm) and medium (400 ppm) levels of carbon disulfide exposure and blood alcohol levels of approximately 0.75%, there is a carbon disulfide inhibition of aldehyde dehydrogenase with an increase in acetaldehyde concentrations in the blood. However, these increased acetaldehyde concentrations were not considered great enough to indicate the Antabuse syndrome. The study authors asserted that the Antabuse syndrome is not likely to occur in subjects who have blood alcohol levels of up to 0.8% and are exposed to 10 ppm carbon disulfide.

AZIDA de BARIO (Spanish) (18810-58-7) Highly unstable in dry form. Dust forms explosive mixture with air. Heat, shock, or friction can cause spontaneous decomposition and explosion. Forms shock-sensitive mixtures with lead and other heavy metals. Contact with barium, iron, or sodium will increase its sensitivity to explosion. Contact with acids forms corrosive hydrogen azide. Reacts violently with oxidizers, carbon disulfide. Commercially available in ethyl alcohol. Keeping the chemical wet greatly reduces its explosion hazard.
