发明名称 TWO-STEP METHOD OF SEPARATING 40-60% OF HYDROGEN PEROXIDE WATER SOLUTION
摘要 FIELD: chemistry. ^ SUBSTANCE: invention relates to chemical technology of inorganic substances, namely to separating 40-60% hydrogen peroxide water solution from oxidate, obtained by oxidation of isopropanol with oxygen-containing gas. Essence of invention: at first stage before vacuum rectification light fraction in amount 0.2-0.6 weight fractions of initial oxidate flow is distilled from oxidate in evaporation column at pressure 65-110 kPa, and vacuum ratification is carried out at residual pressure 25-65 kPa. ^ EFFECT: increase of hydrogen peroxide output and reduction of energy consumption. ^ 2 dwg, 2 tbl, 4 ex
