- 中文摘要:
焦油經濃硫酸璜化後,在聚葡萄糖(Sephadex)中層析分餾,由其分子量之分佈曲線判斷,應
為數種不同高分子物之混合體。
′焦油經高溫鹼液水解處理,並以紅外線分光法協助測定生成品,證實有苯甲酸,苯酚,?苯二
酚及醛類等存在。
依據上項試驗結果,推測焦油之結構,以脂化酚類之聚合體為主,並擬具四種可能性之脂化結
構。
e - 英文摘要: After the sulfonation the sulfonated tar was fractionated in a column filled withSephadex. It has been observed that the tar may be composed of four kinds ofpolymers of different compositions. The tar was hydrolyzed with alkali under nitrogen atm. at elevated temp. andpressure. The products consist of four compounds:benzoic acid, phenol, catecholand a certain kind of aldehydes. Four kinds of structure formula were proposed.
