摘要
采用GC/MS方法测定了单体酸的主要组成:用甲酯化后的试样进行GC/MS分析,鉴定出肉豆蔻酸(12.16%)、棕榈酸(8.51%)、十八稀酸(25.53%)、硬脂酸(32.72%)等15种物质。从评价铝材轧制油添加剂的性能指标——相容性、润滑性、抗磨性、退火清洁性和抗氧化性5个方面,考察了将单体酸作为或加工成为铝材轧制油添加剂的可行性。
The chemical composition of fatty acids in monomer acid was determined by GC/MS. After the monomer acid sample was etherified by methanol, the relative contents of fatty acids in it were analyzed with GC/MS. Fifteen components （such as myristic acid, palmitic acid, oleic acid and stearic acid ） were identified. The analysis results showed that tetradecanoic acid content was 12.16%, hexadecanoic acid content was 8.51%, octadecenoic acid content was 25.53% and octadecanoic acid content was32.72%. The feasibility of using the monomer acid as lubricant additive in aluminium rolling was studied. The rolling oil performance was comprehensively evaluated by taking the following five performance indices： compatibility, lubrication, tribological property, annealing property and anti-oxidation. The results showed that the comprehensive effects of the additive were excellent.
