Abstract

1391352 Heat transfer medium NIPPON PETROCHEMICALS CO Ltd 23 June 1972 [8 July 1971] 29435/72 Heading C4X In a heat transfer process the heat transfer medium comprises one or more aromatic hydrocarbons of formula wherein each of R 1 and R 2 is H, CH 3 or C 2 H 5 , at least one of R 1 and R 2 being CH 3 or C 2 H 5 . The hydrocarbons may be obtained by the reaction of styrene with xylene or another, C 8 aromatic, e.g. ethylbenzene, or toluene.
