The synthesis of furil from 2-furaldehyde using VB1 as the catalyst and CuSO4.5H2O-pyridine as the oxidant was studied.

以糠醛为原料，VB1为催化剂，利用安息香缩合反应合成糠偶姻，再用硫酸铜-吡啶氧化得到糠偶酰。

A proper composition of the plating solution was obtained as follows: copper sulfate 16 g／L,EDTA·2Na 30 g／L,glyoxylic acid 13 g／L,2,2'- bipyridine 10 mg／L.

优化工艺条件：硫酸铜16 g／L，乙二胺四乙酸二钠30 g／L，乙醛酸13 g／L，2，2′-联吡啶10 mg／L，pH 12.5，温度 40℃。

Treatment with 4 to 10ppm CuSO4 within less than 5min, proved effective to kill Gymnodinium.

裸甲藻可采用硫酸铜溶液处理，浓度4～10ppm，处理时间小于5min。

The preparation of zinc sulfate heptahydrate and copper sulfate pentahydrate from calcined zincblende was investigated.

用经高温煅烧后的闪锌矿石与稀硫酸反应制备七水硫酸锌和五水硫酸铜。

The optimum reaction conditions were that the molar ratio of maleic anhydride and p-nitroaniline was 1.2:1, the volume ratio of toluene and DMF was 10:1, the amination temperature was 20~30℃ the cyclization temperature was 145~150℃ and the cyclization time was 6 h over; the amount of p-toluene sulfonic acid was 12% of total reactant mass, the amount of copper sulfate was 0.1~0.5% of total reactant mass, the amount of hydroquinol was 0.1% of total reactant mass.

得到的最佳工艺条件是：n：n为1.2：1，V：V为10：1；胺化反应温度为20~30℃，环化反应温度为140~150℃，环化反应时间为6h以上；对甲基苯磺酸用量为反应物总质量的1%~2%；硫酸铜用量为反应物总质量的0.1%~0.5%；对苯二酚用量为反应物总质量的0.1%。

Therefore can pass to use the cupric sulfate sulfuric acid potassium for the catalyst take sulfuric acid as to carry the body to digest it, make the amino acids chelate match the conversion for dissolve sex easily of ammonium sulfate and white vitriol, then absorb a fixed amount to try the kind to join 40% sodium hydroside combine under the steam heat function make ammonia the spirit swims to leave out, through cool off to respond the born boric acid with boric acid, be got the total nitrogen content by the standard aqua titration of hydrochloric acid immediately after;But the white vitriol can immediately join the hydrochloric acid hydroxylate , fluoride to turn the in order to cover up, carry on the titration but get the content of its zinc with the EDTA mark liquid..

因此可以通过用硫酸铜硫酸钾为催化剂以硫酸为载体将其消化，使氨基酸螯合锌转化为易溶性的硫酸铵和硫酸锌，然后吸取一定量的试样加入40 %的氢氧化钠并在水蒸气高温作用下使氨气游离出来，经冷却与硼酸反应生成硼酸铵，接着由盐酸标准溶液滴定得到总氮含量；而硫酸锌即可加入盐酸羟铵、氟化氢铵为掩蔽剂，用EDTA标液进行滴定而得到其锌的含量。

All the above results indicate significantly that the copper, nickle and zinc can be separated successfully by this technology and the three products of copper sulfate, zinc sulfate and nickelous sulfate are finally obtained.

整条工艺完成了铜、镍和锌3种主要离子间的分离，得到硫酸铜、硫酸锌和硫酸镍3种产品。

Again determines the low temperature phosphorization formula through the orthogonal experiment: The zinc oxide is 8.00g/L, the phosphoric acid is 0.07mol/L, the nitric acid is 0.06mol/L, the nickelous nitrate is the 1.00g/L
