摘要
油品添加剂色泽过深多年来一直是困扰我国添加剂发展的一大难题,它可导致产品销售不畅,造成较大经济损失,使国产润滑油添加剂面临着失去市场竞争力的威胁。通过对烷基酚原料进行选择及羧基化工艺进行优化,确定了较佳的烷基水杨酸盐色泽改进工艺,所得烷基水杨酸盐产品的外观色泽有一定程度的改善,色度较原产品降低2个单位,产品的综合性能也得到较大提高。
The dark colour of lubricating oil detergents stunts not only the development of domestic additive industry for many years but also sales of the products,which results in benefit loss and market competitive power loss.The improved technic of colour for alkyl salicylate is determined by selecting the alkyl phenol and optimizing the carboxylation reaction techology.The improved products have meliorative colour that the chroma is lower than that of traditional products by two units,and the integrated performances are improved greatly as well.
