The invention discloses using an excess amount of catalyst is to cause formation of a semisolid grease in a transesterification reaction. Transesterification is known from the field of biodiesel production, where a minimum amount of catalyst is used to maximize the yield of methylesters, while minimizing the production of glycerol waste. However, rather than producing waste glycerol, the process according to the invention produces a highly useful glycerol grease, which for instance has excellent lubricating properties. For example, the new grease is useful as a chainsaw lubricant, widely surpassing known products in the field both in mechanical properties and environment. |
