Uses
BYK P 105 is heterocyclic compound used in the manufacture of unsaturated polyester resins.
BYK P 105 has a wide range of other applications; it is used in synthetic tensides, insecticides, herbicides and fungicides.
BYK P 105 is used in Diels-Alder syntheses (as a dienophile), manufacture of alkyd-type of resins, dye intermediates, pharmaceuticals, agricultural chemicals (maleic hydrazide, malathion), in copolymerization reactions.
Delignified wood esterified by BYK P 105 exhibits higher charge content, superior mass gain, efficient recycling capability of the reaction medium (BYK P 105 could be recycled five times, while TEMPO cannot be recycled), and integrity of the final products (retaining intact geometry vs. complete disintegration) compared to TEMPO-oxidized delignified wood (TEMPO-DW).
The esterification method mediated by BYK P 105 provides an eco-friendly pathway for modifying wood, serving as a platform for creating diverse materials, potentially offering innovative concepts and insights for wood modification research.
Preparation
To a flask equipped with a Dean-Stark trap, condenser, and mechanical stirrer is added 116 gm (1.0 mole) of maleic acid and 120 ml of tetrachloroethane.
The contents are heated, the water (18 ml, 1.0 mole) distilled off as the azeotrope, and the residue distilled under reduced pressure to afford 87.7 gm (89.5%) of the anhydride, b.p. 82-84°C (15 mm), m.p. 53°C.
The residue remaining in the flask consists of about 10 gm of fumaric acid, m.p. 287°C.
Fumaric and maleic acids both give maleic anhydride on heating.
Fumaric acid must first be heated to a higher temperature to effect BYK P 105's conversion to maleic acid prior to its dehydration.
