润滑油金属清净剂是内燃机油不可缺少的一类主要添加剂。磺酸盐是国内外润滑油添加剂中用量最大品种之一,高档内燃机油采用的磺酸盐一般是磺酸钙和磺酸镁。而髙碱值合成磺酸钙添加剂具有优异的酸中和能力和较好的高温清净性,是内燃机油中必不可少的添加剂。
本论文以烷基苯磺酸、氢氧化钙、氧化钙和二氧化碳为原料,甲苯为溶剂,甲醇为促进剂,采用多步碳酸化法,制备髙碱值烷基苯磺酸钙。通过正交实验对髙碱值烷基苯磺酸钙合成方法进行研究,考察了四种不同产地的磺酸原料对中性盐、T105(300)、T106(300)的影响,并研究了国内磺酸与国外磺酸不同配比、原料水的用量、二氧化碳通入速率、不同溶剂对合成髙碱值磺酸钙的影响。
Engine oil lubricants metal detergent is an indispensable principal additives. Sulfonate is the largest amount of foreign species in the lubricant additive one, high-grade engine oil is generally used sulfonate sulfonic acid calcium and magnesium. The base value Gao synthetic calcium sulfonate additive has excellent acid neutralization capacity and good high temperature detergency, is an essential engine oil additives.
In this thesis, benzene sulfonic acid, calcium hydroxide, calcium oxide and carbon dioxide as raw materials, toluene and methanol as promoter, a multi-step carbonation method, preparation Gao base value of calcium alkyl benzene sulfonate. Gao orthogonal experimental base value of calcium alkyl benzene sulfonic acid synthesis study examined four different areas of the acid salts of neutral material, T105 (300), T106 (300) of the impact and the domestic sulfonic acid with different ratio of foreign raw materials usage of water, carbon dioxide leads to rates of different solvents on the synthesis of base value Gao acid calcium.

Lubricants metal clean agent is internal combustion engine oil indispensable kind of major additives. Sulfonic acid salt is in the domestic and international lubricant additives, one of the most consumable varieties of high-grade engine oil sulfonates is commonly by calcium lignosulfonate and sulfonic acid magnesium. But high alkali value calcium lignosulfonate additive synthesis has excellent acid neutralization ability and better high temperature detergency, is an indispensable additive engine oil.
In this paper, calcium hydroxide lauryl benzene sulfonic acid, cao and carbon dioxide as raw materials, toluene as solvent, methanol as acclerant, adopt the method, many steps carbonate preparation high alkali value alkyl benzene sulfonic acid calcium. Through orthogonal experiments of high alkali value alkyl benzene sulfonic acid calcium synthetic methods, inspected the four different raw material on the origin of q235 carton steel acid (300), and T105 T106 (300) influence, and studied abroad and domestic sulfonic acid different proportion, raw material the dosage of the water, carbon dioxide access to rate, different solvents on synthetic high alkali value of calcium lignosulfonate influence.

The lubricating oil metal pure medicinal preparation is internal combustion engine fuel essential kind of main chemical additive. The sulfonate is in the domestic and foreign oil dope one of amount used biggest varieties, the upscale internal combustion engine fuel uses the sulfonate is generally the sulfonic acid calcium and the sulfonic acid magnesium. But 髙 the alkalinity synthesis sulfonic acid calcium chemical additive has the outstanding acid neutral ability and good high temperature pure, is in the internal combustion engine fuel the essential chemical additive. the present paper take the alkyl benzene sulfonic acid, the calcium hydroxide, the calcium oxide and the carbon dioxide as raw material, the toluene is the resolver, the methyl alcohol is the promoter, uses many step carbonic acid reductions, the preparation 髙 alkalinity alkyl benzene sulfonic acid calcium. Conducts the research through the orthogonal experiment to 髙 the alkalinity alkyl benzene sulfonic acid calcium synthetic method, inspected four kind of different habitat sulfonic acid raw materials to the neutral salt, T105 (300), T106 (300) the influence, and has studied domestic sulfonic acid and the overseas sulfonic acid different allocated proportion, raw material water amount used, the carbon dioxide passes over the speed, the different resolver to synthesize 髙 the alkalinity sulfonic acid calcium influence.
