Production of CAS 85-43-8 | 1,2,3,6-Tetrahydrophthalic anhydride
Maleic anhydride was added to the reactor for heating and melting, and then slowly butadiene was introduced at about 100°C, and a certain amount of butadiene was introduced for intermediate control. After the reaction was completed, the product was obtained by cooling and crystallization.
