(1)乙醇在銅或銀做催化劑條件下發(fā)生催化氧化生成乙醛和水,反應(yīng)的方程式為2CH3CH2OH+O2
Cu或Ag
△
2CH3CHO+2H2O,故答案為:2CH3CH2OH+O2
Cu或Ag
△
2CH3CHO+2H2O;(2)葡萄糖在水浴加熱條件下發(fā)生銀鏡反應(yīng),反應(yīng)的方程式為CH2OH(CHOH)4CHO+2[Ag(NH3)2]OH
60~70℃
水浴
CH2OH(CHOH)4COONH4+2Ag↓+3NH3+H2O,故答案為:CH2OH(CHOH)4CHO+2[Ag(NH3)2]OH
60~70℃
水浴
CH2OH(CHOH)4COONH4+2Ag↓+3NH3+H2O;(3)葡萄糖和新制氫氧化銅在加熱條件下發(fā)生反應(yīng)生成葡萄糖酸和氧化亞銅,反應(yīng)的方程式為CH2OH(CHOH)4CHO+2Cu(OH)2
△
CH2OH(CHOH)4COOH+Cu2O+2H2O,故答案為:CH2OH(CHOH)4CHO+2Cu(OH)2
△
CH2OH(CHOH)4COOH+Cu2O+2H2O;(4)淀粉在稀硫酸作用下水解生成葡萄糖,水解的方程式為(C6H10O5)n+nH2O
稀硫酸
nC6H12O6,故答案為:(C6H10O5)n+nH2O
