The invention concerns compositions comprising a mixture of mono- and polybenzyl-1,2,3,4-tetrahydronaphthalenes. The invention also concerns said compositions or a mixture of monobenzyl-1,2,3,4-tetrahydronaphthalene isomers as heat transfer fluid. Said compositions or the mixture of monobenzyl-1,2,3,4-tetrahydronaphthalene isomers are obtained by the action of benzyl chloride on 1,2,3,4-tetrahydronaphthalene in the presence of FeCl<SUB>3</SUB>. |
