采用超声波反应器,以邻苯二酚、三甘醇和对甲基苯磺酰氯等为原料,二甲亚砜为溶剂,氢氧化锂为催化剂兼模板剂,合成单苯并-12-冠-4（Benzo-12-crown-4 B12C4）。产物经IR、1H NMR、MS和元素分析等表征。合成收率达到23%。较之传统方法具有操作简单、反应时间短、反应条件温和、无需氮气保护等优势。
採用超聲波反應器,以鄰苯二酚、三甘醇和對甲基苯磺酰氯等為原料,二甲亞砜為溶劑,氫氧化鋰為催化劑兼模闆劑,閤成單苯併-12-冠-4（Benzo-12-crown-4 B12C4）。產物經IR、1H NMR、MS和元素分析等錶徵。閤成收率達到23%。較之傳統方法具有操作簡單、反應時間短、反應條件溫和、無需氮氣保護等優勢。
채용초성파반응기,이린분이분、삼감순화대갑기분광선록등위원료,이갑아풍위용제,경양화리위최화제겸모판제,합성단분병-12-관-4（Benzo-12-crown-4 B12C4）。산물경IR、1H NMR、MS화원소분석등표정。합성수솔체도23%。교지전통방법구유조작간단、반응시간단、반응조건온화、무수담기보호등우세。
The synthesize of benzo-12-crown-4（B12C4）using ultrasonic wave was described.The triglycol,pyrocatechol and 4-methylphenylsulfonyl chloride were chosen as raw materials,dissolved in dimethyl sulfoxide and then reacted in special ultrasonic wave.The lithium hydroxide was also dissolved in it which acts as the template reagent and base（catalyst）.The product B12C4 was characterized by IR,1H NMR,MS and element analysis,and its yield was 23%.Compared with the traditional synthetic methods,it had the advantages of milder reaction conditions,shorter reaction time and fewer steps.
