To be different from the already chloromethylation catalyst, it has a certain amount of moisture wet, which will not produce huge amounts of doughtic cancerogenic chloromethyl methyl ether during and after the reaction.4,4\'-bisbiphenyl, 1,4-bisbenzene, 1,4-bis(chloro- methyl)-2,5-dimethylbenzene, 1,5-bis-2,4-dimethylbenzene, 4-(chlor- omethyl)-1,2-dimethylbenzene, 1,2-bis-4,5-dimethylbenzene, 5,8-bis-1,2,3,4-tetrahydronaphthalene, 3,3\',5-tris-4,4\'-bisbiphenyl and 3,3\', 5,5\'-tetrakis-4,4\'-bisbiphenyl were synth- esized by using this new catalyst. Results indicated that when the reaction temperature was 55～60℃, the reaction time was 12h, the catalyst which consists of the concentration of 80%H_2SO_4, HAc and Lewis acid, the amount of Lewis acid 0.15 mol(nLewis:nbiphenyl=1.5:1), yield of biphenyl chloromethylation product 4,4\'-bis(chrolomethylbiphenyl can reach a maximum 85%.

采用这种催化体系完成了4，4′-二氯甲基联苯、对二氯甲基苯、1，4-二氯甲基-2，5-二甲基苯、1，5-二氯甲基-2，4-二甲基苯、4-氯甲基-1，2-二甲基苯、1，2-二氯甲基-4，5-二甲基苯、5，8-二氯甲基-四氢萘、3，3'，5-三氯甲基-4，4'-二甲基苯和3，3'，5，5'-四氯甲基-4，4'-二甲基苯的合成，结果表明：在反应条件为：反应温度55～60℃，反应时间12h，选择80%H_2SO_4、冰醋酸和Lewis酸为催化剂，反应最佳反应Lewis酸用量是0.15mol(和原料比为1.5：1)，反应效果最好，联苯氯甲基化产物(4，4′-二氯甲基联苯)收率为85%；在反应条件为：反应温度70℃，反应时间8h，80%H_2SO_4、冰醋酸和Lewis酸为催化剂，反应最佳反应Lewis酸用量是0.1mol(和原料比为1：1)时，反应效果最好，苯的氯甲基化产物收(来源：ABd0C论文eded网www.abclunwen.com)率为75%；在反应条件为：在反应条件为：反应温度40℃，反应时间10h，60%H_2SO_4和Lewis酸为催化剂，反应最佳反应Lewis酸用量是0.1mol(和原料比为1：1)时，反应效果最好，对二甲苯氯甲基化产物(1，4-二氯甲基-2，5-二甲基苯)收率为78.5%；在反应条件为：反应温度35℃，反应时间10h，60%H_2SO_4、冰醋酸和Lewis酸为催化剂，反应最佳反应Lewis酸用量是0.1mol(和原料比为1：1)时，反应效果最好，间二甲苯氯甲基化产物(1，5-二氯甲基-2，4-二甲基苯)收率为81.5%。

There are some grass seeds recommended for ecological restoration , for example, Kentucky bluegrass, ryegrass, coronilla, festuca arundinacea, sword-bamboo and euonymus fortunei.3Regarding JBA,YQS, and CXL fertilizer as addition agent of the ecological material, magnetic fertilizer as ecological fertilizer, the material take on character such as water holding capacity, fertilizer retaining, prime cluster structure and binding power, which realize the destination of ecological protection of the abrupt rock slope.4Ecological material protection slope techniques, which is suitable for abrupt rock slope in high-cold area, has been formed elementarily.

高寒地区生态护坡的草种应选用具有抗寒、抗贫瘠和适宜粗放管理的冷季型草种，推荐使用的川西高寒地区生态护坡植物种属为：草地早熟禾、黑麦草、小冠花、高羊茅的草种组合，剑竹灌木种，以及小叶扶芳藤藤蔓植物种。(3)适当配比的高分子材料JBA、YQS和生态肥料CXL作为生态基材的添加剂可使基材具有保水、保肥、优质团粒化和粘结性能，从而达到生态护坡的目的。(4)开发了JYC生态护坡基材，初步形成了一套适合川西高寒地区岩质陡边坡生态基材防护的技术方法体系。来源：Ac9BC论文网www.abclunwen.com
