Abstract

1285259 Heat-transfer oils; propyl naphthalenes KUREHA KAGAKU KOGYO KK 20 Nov 1970 [20 Nov 1969] 55364/70 Headings C4X and C5E In a heat-transfer process, the heat-transfer oil employed comprises at least 60% by wt. of one or more propyl naphthalenes, preferably of the specification:-B.Pt. 250-350‹ C.; solidification point - 70‹ to - 30‹ C.; av. mol. wt. 160 - 260; S.G.(d 4 <SP>15</SP>) 0À94-0À98; ignition pt. 110- 170‹ C.; viscosity 0À5-4À0 cp at 100‹ C. Monopropyl naphthalene alone or a mixture of mono-, di- and tripropyl naphthalenes may be used. The balance, if any, of the oil may be polycyclic aromatics and derivatives thereof. Examples 1 and 2 disclose the reaction of liquid propylene with naphthalene in the presence of a SiO 2 /Al 2 O 3 catalyst to produce a crude propylated naphthalene mixture, which is distilled under reduced pressure to a fraction comprising monopropyl naphthalene and minor amounts of di- and tripropyl naphthalene.
