Description
durante la adición del primer equivalente de 2,6-di-terc-butil-4-metoximetilfenol, pero remitió cuando continuó la adición. Se agitó la mezcla de reacción a temperatura ambiente durante 3 horas. El análisis de RMN mostró la conversión completa de los materiales de partida. Se separó la fase ácida y se lavó la fase orgánica con agua (20 ml), hidróxido de sodio diluido hasta pH 7-8, agua (20 ml) y se secó sobre sulfato de magnesio. La evaporación del 5 disolvente bajo presión reducida procuró un aceite viscoso que solidificó por reposo a temperatura ambiente, p.f., 54 ºC. El análisis de HPLC mostró isómero monosustituido (13 %), isómero disustituido (18 %), isómero trisustituido (19 %), isómero tetrasustituido (32 %) e isómero pentasustituido (11 %). Además, se identificó un 6 % de productos con puente de metileno y otros materiales oligoméricos en el producto. El tiempo de inhibición de la oxidación medido por PDSC a 160 ºC era de 72 minutos a 0,25 % en peso, de 115 minutos a 0,50 % en peso y de 174 minutos
10 a 0,75 % en peso de carga.
