To obtain a new terpene ether having a specific structure, having a substantially low freezing point in spite of having a high mol.wt., exhibiting improved behaviors at low temperatures and useful as a traction fluid, a fragrance and a solvent.
The new terpene ethere is a compound of formula I [(m) is 2-5; A is a 2-5C alkylene; R is H, a (substituted) 1-4C alkyl, a (substituted) 5-12C cycloalkyl or the like], for example, diethylene glycol isobornyl ether. The compound of the formula I is preferably obtained by reacting (A) caffeine with (B) an alcohol of formula II (for example, diethylene glycol) in the presence of an acidic catalyst (for example, a mineral acid such as sulfuric acid) in an inert solvent such as pentane at a reaction temperature in the range of room temperature to 160°C.
