Ivermectins ( a mixture containing more than 80 % of 22, 23 - dihydroavermectin bla and less than 20 % of 22, 23 - dihydroavermectin b1b ), which have the same effective antiparasitic activities and the lower level of toxic side - effects than avermectins, are currently synthesized by chemically reducing the double bond between c22 and c23 of avermectins b1
阿維菌素b1在c - 22 ， 23位的化學加氫還原產物稱為伊維菌素（ ivermectins ） ，具有與阿維菌素相同的殺蟲活性，但毒性更低，更安全。目前國內外報道的伊維菌素生產均是用化學還原法，生產成本很高。The conclusions are as follows : ( 1 ) high - pressure water - atomization can be used to produce a pre - alloyed steel powder with high apparent density, high green strength, size - stability after sintering and low hydrogen - loss content ; ( 2 ) the higher smelting temperature and / or water pressure, the finer particle size of steel powders ; ( 3 ) when the atomization angle holds in a reasonable value ' s range the obtained powder will have a better particle size distribution ; ( 4 ) an optimum atomization technological parameters : liquid steel flux, water pressure and water prick angle was obtained ( 5 ) reduction variables ( temperature, holding time, material - bed ' s thickness and reducing gas flux ) have a significant effect on the particle agglomeration and properties of final powder was given ( 6 ) different alloying methods were developed to modify properties of ferrous powder materials and hence to broaden its applications in ferrous powder metallurgy industry
本文系統研究了水霧化預合金鋼粉生產工藝及合金化方法對鐵基粉末冶金材料性能影響，詳細研究了冶煉、霧化、還原工藝參數對預合金鋼粉化學成份和物理性能影響，並得出如下結論： （ 1 ）採用高壓水霧化技術可用於生產高密度、高強度、尺寸穩定性的低氫損含量的水霧化預合金鋼粉。 （ 2 ）冶煉溫度越高，高壓水壓力越大，所得生粉顆粒粒度越細。 （ 3 ）水錐角調整在一個適當角度范圍內可獲得粒度組成較好的生粉。Sodium hydroxyde for industrial use. determination of sulphur compounds. method by reduction and titrimetry
