benzoquinone

基本解釋

Primary by-products range from benzoquinone to maleic acid and oxalic acid.
中間產(chǎn)物主要為苯醌、馬來酸、草酸等，
Their intermediates included benzoquinone,adjacent diphenol and hydroquinone.
這兩個(gè)反應(yīng)的中間產(chǎn)物都是苯醌、鄰苯二酚和對(duì)苯二酚;
The in-situ formed Pd(0) was efficiently converted to the catalytically active Pd(II) species by benzoquinone in HOAc.
這種情形下產(chǎn)生的鈀（0）在醋酸中能夠被苯醌高效地修飾成有催化作用活性的鈀(II)類物質(zhì)。
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%.
對(duì)苯二酚和甲醇在濃硫酸和對(duì)苯醌催化下,制得4-甲氧基酚,產(chǎn)率為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.
以苯酚為原料,復(fù)合金屬離子為催化劑,研究用氣相氧化合成苯醌,用鐵粉還原苯醌制對(duì)苯二酚的兩步法工藝,考察了氧化過程中的工藝條件對(duì)反應(yīng)的影響。
