Question

由丙烯合成2,4—戊二醇～原料自选CH3—CH=CH2———>CH3-CH（OH）-CH2-CH（OH）-CH3

Answer 1

CH3—CH=CH2 + Cl2 (高温, 自由基反应, 工业制法） = ClCH2-CH=CH2 + HCl

ClCH2-CH=CH2 + Mg = CH2=CH-CH2MgCl

CH2=CH-CH2MgCl + CH3-CHO = CH2=CH-CH2-CH(OH)-CH3

CH2=CH- CH2-CH(OH)-CH3 + HCl = CH3-CH(Cl)- CH2-CH(Cl)-CH3

CH3-CH(Cl)- CH2-CH(Cl)-CH3 + H2O + NaOH = CH3-CHOH-CH2-CHOH-CH3
