Effects of palmityl palmitate on the proliferation of human peripheral blood monocytes 棕榈酸棕榈酯对人外周血单核细胞增殖的影响
Ultrafine WO_3 powders were prepared by colloidal chemical method using sodium tungstate, hydrochloric acid and palmityl trimethyl ammonium bromide as starting materials. 本文以钨酸钠、盐酸和十六烷基三甲基溴化铵为原料,采用胶溶法制备了WO3超细粉体。
The esterification of AZT was carried out in dry dichloromethane with palmityl chloride at room temperature. The product were chromatographed over silica gel columns and purified by means of recrystallization. The purity of product exceeded 99%. 将AZT溶于干燥二氯甲烷中,与棕榈酰氯在室温下经酯化反应制得AZTP,硅胶柱层析将产物分离,并以重结晶法精制,其纯度在99%以上。
