Formaldehyde → Xylene formaldehyde

Participants

Reaction Steps

A reactor was charged with 106 g of m-xylene, 129 g of a 37% aqueous solution of formaldehyde (formalin) and 98% by weight sulfuric acid, and the reaction was started at 95° C. with stirring. The reaction was performed for 7 hours, and the temperature finally rose to 104° C. After the end of the reaction, the aqueous phase at the bottom (sulfuric acid phase) was separated, and the resulting oil phase was steam-distilled at 100° C. at atmospheric pressure. 107 g of a xylene/formaldehyde resin was obtained.
