摘要：
A tehcnological process for obtaining commercial-grade ethanol from the waste waters of silicon dioxide production is proposed. The process includes combined treatment of the liquid phase with calcium chloride (or dilute sulfuric acid) and hydroxylamine and subsequent fractionation in a packed column with an efficiency of 30 theoretical plates for the minimum possible reflux ratio.
