制备方法与用途

化学性质
本品为白色或微黄色粉末。

用途
作为铬雾抑制剂,本品在电镀铬过程中定量加入,电解时会形成一定厚度的细密泡沫层,有效抑制酸雾放出,从而保护环境并节约铬酐。

生产方法
将无水氟化氢加入电解槽中,在15V左右进行电解干燥。当电流降至一定值后,加入辛基磺酸,并控制电压4~15 V、电流强度0.1~2A及温度10~15 ℃,开展电化学氟化反应。定期从底部放出反应生成物并补充原料,直至极板钝化为止。最终产物为辛基磺酸氟,经精制后备用。

在洗盐釜中,先加入95%乙醇和等体积的去离子水,再添加适量氢氧化钾和氧化钙,升温至70 ℃。搅拌下缓慢滴加计量的辛基磺酸氟,待pH值达到7时终止反应,趁热过滤除去滤渣,并冷却结晶、过滤、干燥后即得成品。

  • Alpha-olefins and olefin polymers and processes therefor
    申请人:——
    公开号:US20030171508A1
    公开(公告)日:2003-09-11
    Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalyzed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear &agr;-olefins by the oligomerization of ethylene using as a catalyst system a combination a nickel compound having a selected &agr;-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected &agr;-diimine nickel complexes with ethylene.
    本文披露了聚合乙烯、无环烯烃、和/或选择性环烯烃,以及可选的烯酸酯或羧酸和其他单体的过程。这些聚合反应由选择的过渡金属化合物催化,有时还有其他辅助催化剂。由于其中一些聚合反应表现出一些活性聚合反应的特征,因此可以轻松制备嵌段共聚物。许多聚合物通常具有新颖的特性,特别是在微观结构方面,这使得其中一些聚合物具有不寻常的性质。披露了许多新颖的催化剂,以及制备它们的一些新颖过程。制造的聚合物可用作弹性体、模塑树脂、粘合剂等。本文还描述了通过使用镍化合物具有选择的α-二亚胺配体和选择的Lewis或Bronsted酸作为催化剂体系,或通过将选择的α-二亚胺镍配合物与乙烯接触来合成线性α-烯烃的合成方法。
