Abstract

The new compounds 1,2,3,4-tetrahydro-2,21-binaphthyl and 1,11,2,21,3,31,4,41-octahydro-2 21-binaphthyl are used as plasticizers for polyvinyl chloride or copolymers of vinyl chloride and vinyl acetate or as plasticizer extenders with dioctyl phthalate. In an example octahydrobinaphthyl is used in amounts of 41-51% by weight with 58,5-48,5% of a 97,5:2,5 vinyl chloride-vinyl acetate copolymer and 0,5% of dibutyltin maleate heat stabilizer.ALSO:The Specification comprises 1,2,3,4-tetrahydro-2,21-binaphthyl and 1,11,2,21,3,31,4,41-octahydro-2, 21-binaphthyl and their preparation by hydrogenating naphthalene at 150 DEG C.-300 DEG C. and a hydrogen pressure of 500-3,000 p.s.i.g. in the presence of at least 0.03% by weight based on the naphthalene of metallic potassium. The potassium may be added as such or formed in situ from sodium and a potassium compound which with the sodium liberates potassium, e.g. the oxide, hydroxide or sulphate. The preferred amount of potassium is 0.5%-3%. Sodium is preferably added in excess when a potassium compound is used or in addition when the metal is used by an amount of 1%-3% of the naphthalene. Tetralin in an amount equal in weight to the naphthalene may be added as solvent. The hydrogenated binaphthyls are recovered by distillation.
