化工知識不僅包含了一般化學知識的內容，還帶有化學生產工藝流程及典型設備的介紹，如接觸法制硫酸，硝酸的工業製法（氨氧化法） ，合成氨工業，電解食鹽水製造氯氣和燒堿，以及電鍍、煉鋁、煉鐵和煉鋼，水泥和玻璃的生產簡介，石油的煉制等，因此，化工知識教學與一般化學知識教學相比，應有其典型的方法。在過去，化工知識的教學一般都採用口頭講解的方法，現在大多數教師也是採用口頭講解的方法，這樣使得化工知識的教學乏味，學生對化工知識的學習缺乏興趣，又因重視雙基，輕實踐，學生對化工知識的學習可以說流於形式。由於多媒體的輔助教學的高效性、形象直觀性、新穎性和多樣性、人工模擬等特點，很適合化工知識的教學，應用多媒體教學化工知識可以解決目前存在的諸多問題，如：模型短缺、組織參觀活動困難、教育經費不足、學生不易觀察等。The isolation and purification of dnaase in the earthworm the earthworm dnaase was purified from the tissue extract of earthworm by denaturing the protein with low ph buffer, high temperature, ammonium sulfate precipitation, deae - cellulose ( de52 ) chromatography and ultra - filter membrane
