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。Standard test methods for soluble cellulose nitrate
