Abstract:
THE INVENTION RELATES TO AN IMPROVED PROCESS FOR THE PREPARATION OF ORGANIC PHOSPHORUS COMPOUNDS HAVING FREE HYDROXY GROUPS AND WHICH ARE USEFUL FOR THE PRODUCTION OF FLAME RESISTANT POLYURETHANE RESINS. PRODUCTION OF ORGANIC PHOSPHORUS COMPOUNDS BY REACTING SPIROCYCLIC COMPOUNDS WITH CARBONYL C OMPOUNDS AND ALKANOLAMINES AND THE UTILITY THEREOF IN THE PRODUCTION OF FLAME-RESISTANT POLYURETHANE RESINS.
Abstract:
A cyclopentene rich fraction, an isoprene rich fraction, and a diolefin (essentially 1,3-pentadiene and cyclopentadiene) rich fraction are recovered from the C5 cut obtained by petroleum cracking. First, said fractions are extracted in a liquid-liquid extraction with 1-oxo-1-methylphospholine. The extractant is then distilled to separate therefrom said fractions.
