Methyl Alkenoate Succinic Anhydride (M-ASA) is the product of the reaction between methyl esters of fatty acids and maleic anhydride. Crude M-ASA was synthesized from rapeseed oil methyl esters. The main compounds in this adduct are methyl oleate succinic anhydride (30%), methyl linoleate succinic anhydride (24%), unreacted methyl esters (41%) and unreacted maleic anhydride (4%). The treatment of wood at high temperature with crude M-ASA conferred protection against fungal decay and insects. Biological tests were carried out on Scots pine (Pinus sylvestris) sapwood and beech (Fagus sylvatica) according to European standards. M-ASA treatment was efficient against mould fungi (BS 3900), blue staining (EN 152), white and brown rot fungi (EN 113), longhorn beetle larvae (EN 46 and 47) and termites (EN 117). This treatment delayed the degradation of wood by soft rot (ENV 807) but it did not prevent it. Therefore, M-ASA combines all the necessary conditions to fulfil the requirements of the biological use classes 2 and 3, but not for class 4.
