【摘要】：硫酸分解氯化鉀制備硫酸氫鉀可在水相和無水相中反應(yīng)進(jìn)行。分別探討了工業(yè)硫酸在兩種工藝條件下,反應(yīng)溫度、原料物質(zhì)的量比、反應(yīng)時間以及硫酸濃度對產(chǎn)品硫酸氫鉀的影響。通過單因素實驗和正交實驗,得到水相最優(yōu)工藝條件:反應(yīng)溫度為90℃、硫酸與氯化鉀物質(zhì)的量比為1.2∶1、反應(yīng)時間為60 min、硫酸濃度為80%(質(zhì)量分?jǐn)?shù),下同),在此條件下轉(zhuǎn)化率可達(dá)98.64%;無水相最優(yōu)工藝條件:反應(yīng)溫度為80℃、硫酸與氯化鉀物質(zhì)的量比為1.1∶1、反應(yīng)時間為60 min、硫酸濃度為70%,此時轉(zhuǎn)化率可達(dá)92%。
[Abstract]:The preparation of potassium bisulfate by decomposition of potassium chloride with sulfuric acid can be carried out in aqueous phase and anhydrous phase. The effects of reaction temperature, ratio of raw materials, reaction time and concentration of sulfuric acid on potassium bisulfate were discussed. Through single factor experiment and orthogonal experiment, the optimum technological conditions of aqueous phase were obtained as follows: reaction temperature 90 鈩，
