查询词典 hydroxide

Jatropha Curcas oil was used as feedstock for producing biodiesel by transesterification,and adding sodium hydroxide,potassium hydroxide or sodium methoxide as catalyst respectively. The optimal conditions were obtained:molar ratio of methanol to oil 6∶1,reaction temperature 60 ℃,reaction time 80 min,mixing intensity 600 r/min,catalyst concentration for NaOH,KOH,or CH3ONa 1.2% of oil weight,The yield of biodiesel was above 97%. The physico-chemical indices of the biodiesel obtained met the quality standard ASTM of USA and DIN V of Germany.

选用了非食用油麻疯果油为原料，以氢氧化钠、氢氧化钾、甲醇钠为催化剂，通过酯交换法制取生物柴油，研究表明最适宜工艺条件为：醇油比6∶1，反应温度60 ℃，反应时间80 min，搅拌强度为600 r/min，催化剂用量为1.2%，转化率达到97%以上，且生物柴油各项理化指标均符合美国和德国测试标准。

First, the cobalt hydroxide is mainly adsorbed on the crystal surface (021) and (100), but not on the main crystal surface (110) of iron hydroxide.

1Co〓在铁黄晶面的沉积主要发生在端面(021)和侧面(100)，而不是(110)晶面。

The iron hydroxide particles prepared above were coated with cobalt by surface adsorption-precipitation reaction. The low pH and Co〓 concentration of suspended system can prevent the nanoparticle from heterocoagulation. The saturation magnetization of MP particles with uniform cobalt hydroxide layer is 10％ higher than that of the α-Fe. And a close SiO〓 layer can improve the coercivity by about 92％.

铁黄粒子表面吸附-反应沉积钴过程中较低的pH值和浓度有利于形成均匀的钴氢氧化物包覆层，可避免形成异相凝聚现象，使比饱和磁化强度提高10％；表面包覆二氧化硅形成致密的薄膜，使矫顽力提高92％。
