摘要：先用硼酸，氢氧化钠配制成硼砂溶液，再用硼砂，硝酸铈，正丁醇和十二醇在二甲苯作为溶剂的体系中反应生成十二烷氧基硼酸铈，最适宜的反应条件是：硝酸铈和硼砂的摩尔比为2:3，酯化反应时间为0.5h，酯化反应温度为130℃，酯交换反应时间为0.5h，反应得到的产物的最高产率为84.01%。利用红外光谱仪分析产物，并在四球试验机上，测定了十二烷氧基硼酸铈添加到基础油后的摩擦磨损性能及十二烷氧基硼酸铈的添加量对这些性能的影响进行了考察，结果表明，含十二烷氧基硼酸铈1.5%（wt%）时，抗磨效果最适宜。测定基础油、添加1.5%（wt%）十二烷氧基硼酸铈的基础油及添加T202的基础油三者的最大无卡咬负荷PB，结果表明添加1.5%十二烷氧基硼酸铈后基础油的PB值最大。最后测定十二烷氧基硼酸铈与T202复配后的摩擦化学性能以及两者的添加量对基础油的摩擦磨损性能的影响，结果表明，当添加1.5%（wt%）十二烷氧基硼酸铈时和添加1%（wt%）T202复配时，润滑油的抗磨效果较好。9303

Tribo-chemical Properties and Synthesis on Cerium Dodecoxylborate
Abstract: The borax is the reaction of orthoboric acid and sodium hydroxide,The cerium dodecoxyborate is the reaction of borax,cerium nitrate,butyl alcohol and dodecanol under the xylene system. The better reaction condition is when the mole ratio of cerium nitrate and borax is 2:3, the esterification reaction time is 0.5h, the reaction temperature is 130℃,the transesterification reaction time is 0.5h and the most prolific  rate of the product is 84.01%.It’s analyszed on cerium dodecoxyborate with IR . On the four ball machine, it’s shown that antiwear and antifriction characteristic were determined on cerium dodecoxyborate added to base oil,on which properties the addition of cerium dodecoxyborate were investigated. It’s shown that wear the better on results,when the content of cerium dodecoxyborate is 1.5%(wt%). It’s determined  the largest non-card bite load PB of base oil, adding 1.5%(wt%) of cerium dodecoxyborate in the base oil and adding the T202's base oil, on results it’s shown that the base oil after adding T202,its PB is maximum. Finally, it’s determined that tribo-chemical characteristic about the compound of cerium dodecoxyborate synergied with T202, the friction and wear performance impact on these two adding amount of base oil.It’s shown that the anti-wear of lubricating oil gains its better effects on results,when add 1.5%(wt%) of cerium dodecoxyborate and add 1%(wt%) of T202 synergied.
