Description

Verfahren zur Befreiung des aus dem Benzolvorlauf gewonnenen Dicyclopentadiens von schwefelhaltigen organischen Verbindungen Dicyclopentadien, das aus Benzolvorlauf gewonnen wird, enthält, wie gefunden wurde, unter Umständen noch geringe Mengen schwefelhaltiger organischer Verbindungen, -die es gelb bis rotorange färben. Die Entfernung dieser Verbindungen gelingt durch Kristallisation des Dicyciopentadiens unter Absaugen der Mutterlauge nicht.Process for the liberation of the dicyclopentadiene obtained from the benzene flow of sulfur-containing organic compounds dicyclopentadiene, that from benzene flow is obtained, as has been found, may still contain small amounts sulfur-containing organic compounds -that color it yellow to red-orange. the These compounds are removed by crystallization of the dicyciopentadiene not with suction of the mother liquor.

Hingegen gelingt sie erfindungsgemäß durch eine Wärmebehandlung beim oder in der Nähe des Siedepunktes des Dicvclopentadiens (17o°) in Gegenwart von Schwermetallverbindungen, wie Quecksilber- oder Bleisalzen, vorzugsweise deren Acetaten oder den Oxyden, mit nachfolgender Wasserdampfdestillation. Die Ausbeute an Beinprodukt erhöht sich, wenn der Zutritt von Sauerstoff während der Wärmebehandlung verhindert wird.On the other hand, according to the invention, it is achieved by a heat treatment at or near the boiling point of dicclopentadiene (17o °) in the presence of Heavy metal compounds such as mercury or lead salts, preferably their acetates or the oxides, with subsequent steam distillation. The yield of leg product increases if the entry of oxygen is prevented during the heat treatment will.

Beispiel 6oo ccm durch schwefelhaltige organische Verbindungen rotorange gefärbtes Dicyclopentadien, das aus Benzolvorlauf gewonnen worden war, wurden mit 30 g gelbem Bleioxyd unter Kohlendioxydschutz 4. Stunden unter Rühren und Rückfauß zum Sieden erhitzt, danach dekantiert und mit Wasserdampf destilliert. Ausbeute an reinem Dicyclopentadien xSS%; 1,3°1o gingen gegen Ende der Wasserdampfdestillation noch gefärbt über.EXAMPLE 600 cc of dicyclopentadiene, colored red-orange by sulfur-containing organic compounds and obtained from benzene forerun, was heated to boiling with 30 g of yellow lead oxide under protection of carbon dioxide for 4 hours with stirring and reflux, then decanted and steam distilled. Yield of pure dicyclopentadiene xSS%; 1.3 ° 1o were still colored towards the end of the steam distillation.
