초록

본 연구에서는 $CCl_4$ 존재하에서 $Cl_2$(g) and ultra violet(200~300nm) 파장으로 maleic anhydride 와 $Cl_2$(g)을 반응시켜 ${\alpha},{\beta}$-dichlorosuccinic acid 를 합성하였다. 그리고 두 번째 반응은 N-(${\alpha},{\beta}$-dichloro)succinic acid 함유 glucosamine 유도체(I)를 합성하는 것으로 methanol 함유 2% acetic acid 용매 하에서 glucosamine과 과량의 ${\alpha},{\beta}$-dichlorosuccinic anhydride을 넣은 후 온도를 $70^{\circ}C$로 올리면서 반응시켰다. 우리는 합성한 유기산 유도체들이 해태 김 재배와 피부미용에 주로 유용하게 활용할 것으로 본다.

${\alpha},{\beta}$-Dichlorosuccinic acid was synthesized through the reaction of maleic anhydride with $Cl_2$(g) and ultra violet(200~300nm) wavelength in the presence of $CCl_4$. The second reaction of N-(${\alpha},{\beta}$-dichloro)succinic acid contained glucosamine derivatives(I) was accomplished by a modification of the general acylation using excess ${\alpha},{\beta}$-dichlorosuccinic anhydride in the presence of 2% acetic acid with methanol as a solvent at elevated temperature($70^{\circ}C$). We considered organic acid derivatives were useful especially of treatment for the cultivating porphyra and skin beauty culture.
