Participants

Reaction Steps

Tetrabromophthalic anhydride (1391.1 grams; 3.0 moles), 2-ethyl-1-hexanol (1171.8 grams; 9.0 moles) and titanium (IV) isopropoxide (7 ml.; 0.5 volume percent on tetrabromophthalic anhydride) were charged into a 3,000 ml. reaction flask maintained under a nitrogen atmosphere. The reaction flask was fitted with a mechanical stirrer. thermometer. nitrogen inlet tube, and a Dean-Stark water trap connected to a Friedrich condensor. The reaction mixture was heated with agitation at a temperature equal or less than about 200° C. for eight hours. The resulting product (2.497 grams) was an amber thick clear liquid having an acidity of 1.4 meq. per 100 grams.
