Hydrogenation of polyallyl alcohol

Polyallyl-type alcohols are hydrogenated by subjecting them in neutral or alkaline solution and in the presence of a catalyst, to the action of hydrogen at a temperature of 100 DEG to 207 DEG C. and a pressure of 500 to 3000 pounds per square inch. The solution in water or methyl, ethyl or isopropyl alcohol is neutralized or rendered alkaline by sodium or barium hydroxide or calcium oxide.

In a modification, acidic polyallyl alcohol solution is refluxed over Raney nickel, the catalyst removed and fresh catalyst used for hydrogenation. Polyallyl alcohol may be prepared by passing air into triallyl borate at 137 DEG C. for 120 hours.

Improvements in or relating to hydrogenated petroleum resins

A non-water-white resin obtained by polymerizing a steam-cracked petroleum naphtha fraction boiling within the range 50-450 DEG F., and from which all the C4 hydrocarbons have been removed, is hydrogenated under such conditions that the colour is decreased towards water-white. A typical fraction comprises aliphatic mono- and diolefins (including cyclic), benzene, toluene, higher aromatic hydrocarbons and paraffins. Hydrogenation is preferably carried out in solution in a volatile solvent at 100-750 DEG F. under a pressure of 100-5000 p.s.i.g. using reduced nickel as catalyst. The polymer resin may be steam-stripped to remove all volatile constituents before hydrogenation. Polymerization may be effected by using clay or a Friedel-Crafts catalyst, or in two stages, using first clay and then a Friedel-Crafts catalyst. It is preferred to remove cyclopentadiene and its lower alkyl homologues before polymerization, preferably by heat soaking to dimerize and distilling to leave the cyclopentadienes ...
