General description

1,2,3,4-Tetrahydronaphthalene (Tetralin), a bicyclic hydrocarbon[1] is a constituent of petroleum and coal tar. It is used in coal liquefaction and as an alternative to turpentine in paints and waxes.[2] Degradation of tetralin by Corynebacterium sp. strain C125,[2] and by pyrolysis have been reported.[3] A study reports the transformation of naphthalene to tetralin in the presence of activated carbon supported molybdenum carbides.[4] Dehydrogenation of tetralin by microwave heating in the presence of platinum-supported activated carbon has been investigated.[5]

Application

1,2,3,4-Tetrahydronaphthalene may be used as a raw material in the synthesis of fullerenes.[6]

Corynebacterium sp. strain C125, originally isolated on o-xylene, was selected for its ability to grow on tetralin (1,2,3,4-tetrahydronaphthalene) as the sole source of carbon and energy. The catabolism of tetralin in Corynebacterium sp. strain C125 was shown to proceed via
