Table. 3. KDP(KH₂PO₄)
The growth of KDP and CuSO₄single crystals were carried out by the temperature decrease method and the constant temperature method. The
method – Wacker process
현재 흔히 이용되고 있는 Wacker process 방법은 ethylene의 부분 산화 반응으로 아래와 같은 반응식을 따른다.
C2H4+2CaCl2+H2O -> CH3CHO+2HCl+2CaCl2
2CaCl2+2HCl+1/2O2 -> 2CaCl2+H2O
반응물로 이용되는 ethylene은 원료비가 비싸고, 공정 과정에서 반응기 부
