摘要： The present invention relates to a process for the production of polymeric sulfur, including a) distilling a mixture of liquid sulfur and a solvent for cycloocta sulfur with a boiling point of less than 444° C. at standard pressure, wherein the bottoms temperature is lower than the boiling temperature of the sulfur and greater than the boiling temperature of the solvent and is at least 120° C.; b) quenching of the sulfur melt obtained as the bottoms product of the distillation according to a) with a non-basic liquid or a mixture of non-basic liquids to a temperature below the melting temperature of sulfur.
