酒石酸钾钠俗称罗谢尔氏盐。分子式KNaC_4H_4O_6·4H_2O,无色透明晶体,易溶于水,水溶液遇醋酸即产生白色沉淀;不溶于乙醇。是一种重要的化工原料,广泛应用于医药、试剂、镀光、制镜、食品、化工、香烟等行业,市场缺口大,供小于求,出口前景好。现介绍用葡萄酒厂下脚料(葡萄皮、梗、酒脚、酒石等)生产酒石酸钾钠工艺。一、生产原理利用葡萄酒下脚料中所含的酒石与碳酸
Potassium sodium tartrate commonly known as Rochelle’s salt. Molecular formula KNaC_4H_4O_6 · 4H_2O, colorless and transparent crystal, easily soluble in water, the case of acetic acid aqueous solution that produces a white precipitate; insoluble in ethanol. Is an important chemical raw materials, widely used in medicine, reagents, plating, mirror, food, chemicals, cigarettes and other industries, the market gap, for less than demand, good export prospects. Now introduced winery waste (grape skins, stems, wine feet, tartar, etc.) production of potassium tartrate sodium process. First, the principle of production The use of wine waste contained in the tartar and carbonated
