ABSTRACT:
Acetals are used as a mineral oil substitute, oil component or base oil in invert-emulsion drilling muds, emulsion drilling muds, engine oils, gearbox oils, lubricating oils and also metal-working fluids, coolants, cooling lubricants and hydraulic fluids. As compared with conventional mineral oils, acetals show good biodegradability and are less toxic.
