The single mechanical seals of five PHP pumps, nine PLA pumps, two THD pumps and nine ZA pumps in the acetic acid plant were changed into dual mechanical seals based on not changing main parts such as casing, impeller, shaft, bearings house etc. to solve the leakage problems of flammable, explosive, poisonous, harmful substances, such as acetic acid, methyl iodide, hydroiodic acid, and propionic acid etc.

通过对醋酸装置中所选用的5台PHP型、9台PLA型、2台THD型及9台ZA型单级卧式脚支撑化工离心泵，在不改变泵壳、叶轮、轴、轴承箱等主要部件的基础上，将原来的单端面机械密封改造为双端面机械密封或串联式机械密封，以此来防止所输送的易燃、易爆、有毒、有害高危介质（如醋酸、碘甲烷、碘化氢、丙酸等）外漏。

In this dissertation, sensitization and its mechanism by some well-known stabilizers, especially 5-methyl-7-hydroxyl-tetraazaindene in silver chloride emulsion have been systematically studied It is found that sensitization by stabilizer is obvious in whatever unsensitized or sulfur-sensitized silver chloride emulsion, as well as fog-inhibition.

When SiO〓-NH〓-Rh-Co complex was used to catalyze the hydroformylation of methyl methacrylate, an optimal conversion of 93.4% and optimal selectivity of 84.4% for the normal aldehyde were both obtained at Rh/Co ratio of 2/1, which were both higher than that catalyzed by SiO〓-SiNH〓-Rh and SiO〓-Si-NH〓-Co momometallic catalysts. Clearly a synergistic action between Rh and Co atoms presented in the complex.

我们以SiO〓-Si-NH〓-Rh-Co催化甲基丙烯酸甲酯的醛化反应，当催化剂中Rh/Co比为2/1时，催化活性最高，可达93.4％，对正构产物β-甲酰异丁酸酯的选择性达到84.4％，都高于单金属催化剂，表明了金属间存在相互作用。
