Aminobenzylphosphonic acid를 포함하고 있는 dipeptide들의 합성을 carbodimide법으로 시도하여 다음과 같은 새로운 화합물들을 얻었다. Glycyl-dl-1-aminobenzylphosphonic acid, alanyl-dl-1-aminobenzylphosphonic acid, L-alanyl-dl-1-aminobenzylphosphonic acid, N-phthalyl-L-phenylalanyl-dl-1-aminobenzylphosphonic acid diethyl ester, N-carbobenzoxyglycyl-dl-1-aminobenzylphosphonic acid diethyl ester, N-carbobenzoxy-alanyl-dl-1-aminobenzylphosphonic acid diethyl ester, N-carbobenzoxy-L-alanyl-dl-1-aminobenzylphosphonic acid diethyl ester, glycyl-dl-1-aminobenzylphosphonic acid diethyl ester hydobromide, alanyl-dl-1-aminobenzylphosphonic acid diethyl ester hydrobromide 및 L-alanyl-dl-1-aminobenzylphosphonic aciddiethyl ester hydrobromide. Ten previously unreported dipeptides ontaining aminobenzylphosphonic acid were prepared by carbodiimide method. These are; Glycyl-dl-1-aminobenzylphosphonic acid, alanyl-dl-1-aminobenzylphosphonic acid, L-alanyl-dl-1-aminobenzylphosphonic acid, N-phthalyl-L-phenylalanyl-dl-1-aminobenzylphosphonic acid diethyl ester, N-carbobenzoxyglycyl-dl-1-aminobenzylphosphonic acid diethyl ester, N-carbobenzoxyalanyl-dl-1-aminobenzylphosphonic acid diethyl ester, N-carbobenzoxy-L-alanyl-dl-1-aminobenzylphosphonic acid diethyl ester, glycyl-dl-1-aminobenzylphosphonic acid diethyl ester hydrobromide, alanyl-dl-1-aminobenzylphosphonic acid diethyl ester hydrobromide and L-alanyl-dl-1-aminobenzylphosphonic acid diethyl ester hydrobromide. The first six compounds were characterized, and the last four compounds were obtained in the crude state.

최근 들어 고체산화물 연료전지(SOFC) 기술이 급성장함에 따라 고온 수증기 전기분해(HTE) 기술이 물로부터 수소를 대량으로 제조할 수 있는 환경 친화적인 기술로 주목 받고 있다 고온 수증기 전기분해는 기존의 액상 전기분해보다 총 에너지 요구량이 작고 전기분해에 필요한 최소의 전기에너지가 온도가 증가할수록 감소하며 고온 수증기 전기분해에 요구되는 에너지의 일부를 전기에너지 대신 열의 형태로 공급이 가능하여 보다 높은 효율을 기대할 수 있다. 따라서 off peak시 기저부하전력을 이용하고, 공정의 열원으로 고온가스의 폐열, 천연가스의 부분산화 반응열 또는 고온 가스원자로의 폐열을 활용하면 SOFC 이용 고온 수증기 전기분해 공정은 수소경제사회에서 요구되는 수소를 대량으로 제조할 수 있는 경제적인 공정이 될 것이다.
A study on the WGS reaction over Pt-Ni based Catalyst
Ryu, Jong Woo,Moon, Dong Ju,Kim, Ahn Na,Lee, Sang Deuk,Lee, Byung Gwon,Ahn, Byoung Sung,Hong, Suck In 한국공업화학회 2004 응용화학 Vol.8 No.1
The WGS reaction over Pt-Ni based catalysts was investigated to develop an alternate commercial Cu-Zn/Al₂O₃ catalyst for an on-board gasoline fuel processor. The catalysts were prepared by coprecipitation and incipient wetness methods, and were characterized by N₂ physisorption, CO chemisorption, XRD, TEM and TPR. It was found that 0.2wt% Pt-40wt% Ni/CeO₂ catalyst showed higher activity and stability than the commercial LTS catalyst, even though both catalysts were deactivated during the thermal cycling runs. The results suggest that 0.2wt% Pt-40wt% Ni/CeO₂ catalyst is an attractive candidate for the alternate Cu-Zn/Al₂O₃ catalyst for automotive applications.
