摘要：

Treating pentaerythrityl tetrachloride with excess hot, highly compressed ammonia yields the tetramine C(CH2NH2)(4) in 57% yield at 52% conversion; unconverted starting material is easily recovered for recycling. The ammonolysis may be conducted either in supercritical ammonia alone or in methanol as the solvent. The product amine is isolated by precipitating it as the water-insoluble disulfate; simply washing the precipitate with water yields disulfate of high purity.
