benzoquinone

基本解释

Primary by-products range from benzoquinone to maleic acid and oxalic acid.
中间产物主要为苯醌、马来酸、草酸等，
Their intermediates included benzoquinone,adjacent diphenol and hydroquinone.
这两个反应的中间产物都是苯醌、邻苯二酚和对苯二酚;
The in-situ formed Pd(0) was efficiently converted to the catalytically active Pd(II) species by benzoquinone in HOAc.
这种情形下产生的钯（0）在醋酸中能够被苯醌高效地修饰成有催化作用活性的钯(II)类物质。
In this work,the 4-methoxyphenol was prepared from hydroquinone,methanol which were catalyzed by benzoquinone and concentrated sulphuric acid.The yield of 4-methoxyphenol was 80%.
对苯二酚和甲醇在浓硫酸和对苯醌催化下,制得4-甲氧基酚,产率为80%25。
The two-step process involving gas oxidation of phenol to benzoquinone with complex metal ions catalysts and reduction of benzoquinone to hydroquinone with iron powder was studied.
以苯酚为原料,复合金属离子为催化剂,研究用气相氧化合成苯醌,用铁粉还原苯醌制对苯二酚的两步法工艺,考察了氧化过程中的工艺条件对反应的影响。
