Aliquat 336 is used as a phase transfer catalyst, [2] including in the catalytic oxidation of cyclohexene to 1,6-hexanedioic acid. [3] This reaction is an example of green chemistry, as it is more environmentally friendly than the traditional method of oxidizing cyclohexanol or cyclohexanone with nitric acid or potassium permanganate, which produce hazardous wastes.
Wilkinson's catalyst is usually obtained by treating rhodium(III) chloride hydrate with an excess of triphenylphosphine in refluxing ethanol. [9] [10] [1] Triphenylphosphine serves as both a ligand and a two-electron reducing agent that oxidizes itself from oxidation state (III) to (V).
Hargreaves: 4 NaCl + 2 SO 2 + O 2 + 2 H 2 O → 4 HCl + 2 Na 2 SO 4. The second major production of sodium sulfate are the processes where surplus sodium hydroxide is neutralised by sulfuric acid to obtain sulfate (SO 2− 4) by using copper sulfate (CuSO 4) (as historically applied on a large scale in the production of rayon by using copper(II ...
SALT I is the common name for the Strategic Arms Limitation Talks Agreement signed on May 26, 1972. SALT I froze the number of strategic ballistic missile launchers at existing levels and provided for the addition of new submarine-launched ballistic missile (SLBM) launchers only after the same number of older intercontinental ballistic missile (ICBM) and SLBM launchers had been dismantled.

Sodium diethyldithiocarbamate typically crystallizes from water as the trihydrate NaS 2 CN(C 2 H 5) 2. 3H 2 O. The anhydrous salt and the trihydrate are often used interchangeably. [1] Sodium diethyldithiocarbamate is obtained by treating carbon disulfide with diethylamine in the presence of sodium hydroxide: CS 2 + HN(C 2 H 5) 2 + NaOH → NaS ...
