Abstract
The appearance and light transmittance of p-hydroxyacetophenone solution were examined by an ultraviolet spectrophotometer after aging test.In this paper,the effects of pH value,temperature and light exposure on the appearance and light transmittance of p-hydroxyacetophenone solution were investigated.The effects of buffer system,sodium metabisulfite and UV absorber on the appearance and light transmittance of p-hydroxyacetophenone solution were also investigated in this paper.The results showed that:the stability of p-hydroxyacetophenone was more affected by light than by temperature;the stability of p-hydroxyacetophenone wais greatly affected by pH value;when pH<6 or pH>7,the color of p-hydroxyacetophenone was very easy to turn yellow;p-hydroxyacetophenone was the most stable pH value of 6.0～7.0;the citric acid/sodium citrate buffer system,sodium metabisulfite and UV absorber could maintain the color stability of p-hydroxyacetophenone.关键词
