Sodium Hydrogen Sulfide NaHS

Selective reduction (e.g., partial reduction of one of two nitro groups) is carried out with an alkali sulfide, such as sodium hydrogen sulfide NaHS ( sodium sulfhy-drate ) or sodium sulfide Na2S, in an aqueous or alcoholic solution. Azo groups are not affected by this method. The reaction converts sodium hydrogen sulfide or sodium sulfide mainly to sodium thiosulfate. [Pg.188]

SODIUM SULFHYDRATE (16721-80-5) NaHS Combustible solid (flash point 195°F/90°C, 73°F/23°C, 45% solution). Hydrolyzes in moist air to sodium hydroxide and sodium sulfide gas. Reacts violently with water, steam, acid, alcohols, producing heat, sodium hydrosulfide solution, and hydrogen sulfide frames spontaneously combustible. Reacts with acids, acid flimes, forming hydrogen sulfide. Incompatible with acids, amides, organic anhydrides, isocyanates, alkylene oxides, epichlorohydrin, aldehydes, alcohols, glycols, phenols, cresols, caprolactam solution, oxidizers. Corrodes most metals in the presence of moisture. On small fires, use dry chemical powder (such as Purple-K-Powder), water spray, or COj extinguishers. [Pg.965]
