An amine of formula (I) which is particularly suitable for use as a curing agent for epoxy resins. The amine of formula (I) is devoid of non-incorporable toxic phenols, and is low-viscosity and pale in colour. It allows the production of easily-workable, low-emission or emission-free epoxy resin products which cure rapidly even at relatively low ambient temperatures thus obtaining a high degree of hardness and a nice surface with hardly any yellowing. This is particularly suited to use in floor or top coatings.

The present invention provides a novel bisphenol compound of formula (I).
wherein R
1
and R
2
are the same or different and are independently either hydrogen or methyl at each occurrence. The present invention also provides a process for preparation of these bisphenol compounds starting from Cashew Nut Shell Liquid (CNSL); —a renewable resource material. The bisphenols prepared in the present invention can be utilized as difunctional monomers for the preparation of various polymers such as epoxy resins, polyesters, polyethersulfones, polyetherketones, polyetherimides, polyarylates, polycarbonates, etc.
Trunk piston marine engine lubrication, when the engine is fueled by heavy fuel oil, is effected by a composition comprising a major amount of an oil of lubricating viscosity and a minor amount of one or more phenolic compounds comprising distilled cashew nut shell liquid or hydrogenated distilled cashew nut shell liquid. Asphaltene precipitation in the lubricant, caused by the presence of contaminant heavy fuel oil, is prevented or inhibited.
