Reaktionsschritte
The S-octyldithiobiuret was prepared as follows: To 135 g of dithiobiuret in 300 ml ethyleneglycol monomethyl ether were added 210 g of n-octyl bromide dropwise at 70°C. After 12 hours the solvent was distilled off at 12 mm. The residue was dissolved in toluene and hexane was added after which the mixture was cooled at 0°C. The solvent was decanted from the semicrystalline precipitate which was dissolved again in glacial acetic acid. The solution was poured on icewater and stirred for 2 hours. The solid was filtered, stirred with hexane in a beaker until it had completely crystallized, filtered and dried. The product had a melting point of 75°-77°C.
