制备方法与用途

简介

戊基黄原酸钾是一种有机硫化合物，化学式为 CH₃(CH₂)₄OCS₂K。它呈现淡黄色粉末状，具有刺激性气味，并且可溶于水。这种物质广泛应用于采矿行业的浮选工艺中。

性质

戊基黄药钾盐在pH 8到13之间相对稳定，在pH值为10时具有最大的稳定性。

应用

戊基黄原酸钾是一种强捕收剂，主要用于需要强捕收力但对选择性要求不高的有色金属矿物浮选。例如，它适用于浮选氧化硫化矿或经过硫化钠和硫氢化钠硫化的氧化铜矿及氧化铅矿。此外，该物质对于处理含金黄铁矿、铜-镍硫化矿等矿石的浮选也能取得较好的效果。

制备

戊基黄原酸钾是通过正戊醇与二硫化碳和氢氧化钾反应制得：

CH₃(CH₂)₄OH + CS₂ + KOH → CH₃(CH₂)₄OCS₂K + H₂O

用途

用作金属选矿中的捕收剂。

  The invention is a process for producing a rubber composition containing at least one rubber component (A) selected from natural rubbers and synthetic diene rubbers, a filler containing an inorganic filler (B), a silane coupling agent (C) and a vulcanization accelerator (D), wherein the rubber composition is kneaded in multiple stages, the rubber component (A), all or a portion of the inorganic filler (B), all or a portion of the silane coupling agent (C) and the vulcanization accelerator (D) are added and kneaded in the first stage of kneading, and the specific energy for kneading in the first stage is from 0.05 to 1.50 kWh/kg. The specific energy is obtained by dividing the power consumption by the motor in the kneading device in the first stage of kneading by the total mass of the rubber composition therein. In the process, the coupling function activity can be further increased and a rubber composition favorably having a low-heat-generation property and having good abrasion resistance can be obtained.
