상업적으로 프로필렌카보네이트를 제조하기 위한 공정 조건 연구
진상현,이학범,백제범 한국에너지학회 2020 에너지공학 Vol.29 No.1
Among the exhaust gas, Carbon dioxide which is a causative factor in greenhouse effect. We study for synthesis of propylene carbonate with carbon dioxide which is captured and utilized incommercially valuable. The Experiment was proceeded as pilot scale with using homogeneous organiccatalyst which is able to produce propylene carbonate in commercial and reaction conditions. Optimizationcondition for concentration of catalyst and reaction temperature, pressure was studied. We confirm thatthis process is eco-friendly method and commercial application due to the mild condition and also catalysthas a competitive price, reusability.
Ambidentate 리간드의 금속착물 (제 5 보). Bis(isonitrosobenzoylacetone)diimine 유도체를 리간드로 하는 니켈(II)착물

니켈(II) 이온 존재하에서 isonitrosobenzoylacetone 과 diamine(ethylenediamine 및 propylenediamine)을 반응시켜 새로운 금속착물들을 합성하고 이들 착물의 구조를 조사하였다. 그 결과 Ni((IBN)$_2$-en((IBA)$_2$-en=N,N'-ethylenebis(isonitrosobenzoylacetone imino))착물에서 리간드의 두 isonitroso기(=N-O) 중에서 한 =N-O는 질소원자를 통하여 금속에 배위되어 5각형 고리를 이루고, 다른 =N-O는 산소원자를 통하여 금속에 배위되어 6각형 고리를 이루고 있다. 그러나 Ni(IBN)$_2$-pn((IBA)$_2$-pn=N,N'-propylenebis(isonitrosobenzoylacetone imino))착물에서 리간드의 두 isonitroso기(=N-O) 모두 질소원자를 통하여 금속에 배위되어 5각형 고리를 이루고 있다. Some nickel(II) complexes have been derived from the condensation of isonitrosobenzoylacetone and diamine(ethylenediamine and propylenediamine) in the presence of metal ion. It is suggested that an isonitroso group(=N-O) of the ligand coordinates to metal through nitrogen atom to form a five-membered ring while other =N-O coordinates to metal through oxygen atom to form a six-membered ring in Ni(IBN)$_2$-en ((IBA)$_2$-en = N,N'-propylenebis(isonitrosobenzoylacetone imino)). But both isonitroso groups of the ligand coordinate to metal through nitrogen atoms to form five-membered rings in Ni(IBA)$_2$-pn ((IBA)$_2$-pn = N,N'-propylenebis(isonitrosobenzoylacetone imino)).
