Description

вых продуктов - пиперилена и формальдегида . ..products - piperylene and formaldehyde. ..

Приме p-i В колбу, снабженную .мешалкой, наливают метанол (251, 695 или 545 г) и внос т 0,1-2 вес.% металлического натри , затем при перемешивании добавл ют диацетат 3-пропеНИЛ-2-ОКСИ-1 ,5-пентадиола. Мольное отношение диацетата (150, 334 или 230 г) к метанолу составл ет от .1:1,2 до 1:1,7. На ректификационной колонне отгон ют смесь метанола и метилацетата в пределах Н.К, при атмосферном давлении. Остаток нейтрализуют уксусной кислотой и разгон ют при 97°С/ /4 мм рт.ст. и выдел ют 4-гексен-1,3-диол (66,6, 149,6 или 103,5 г), 0,9953; 1,4643. Выход 88,4 89,0 или 89,3% соответственно.Example pi In a flask equipped with a stirrer, methanol (251, 695 or 545 g) is poured and 0.1-2 wt.% Of metallic sodium are added, then 3-propynyl-2-OXY-1 diacetate is added with stirring. pentadiol. The molar ratio of diacetate (150, 334 or 230 g) to methanol is from .1: 1.2 to 1: 1.7. On a distillation column, a mixture of methanol and methyl acetate is distilled within H.K., at atmospheric pressure. The residue is neutralized with acetic acid and accelerated at 97 ° C / / 4 mm Hg. and 4-hexene-1,3-diol (66.6, 149.6 or 103.5 g), 0.9953; 1.4643. Output 88.4 89.0 or 89.3%, respectively.
