Trimethylstannyl-diethylamine, -ethylsulfide, -methoxide 및 -hydroxide 등과 phenyl-isocyanate를 여러 온도에서 반응시킨 결과, $100^{\circ}C$ 이하에서는 triphenylisocyanurate만이 생성되었고, $150^{\circ}C$에서는 triphenylisocyanurate 와 diphenylcarbodiimide가 생성되었다. 한편, trimethylstannyldiethylamine과 chloral과의 반응에서는 N,N-diethylformamide와 trimethylstannyltrichloromethide가 생성되었으며, N-ethyl-N'-phenylcarbodiimide가 생성하였다. Trimethylstannyl-diethylamine, trimethylstannylethylsulfide, trimethylstannylmethoxide and trimethylstannylhydroxide were reacted with phenylisocyanate at various temperatures. The product was only triphenylisocyanurate below $100^{\circ}C$ and the mixtures of triphenylisocyanurate and diphenylcarbodiimide were obtained at $150^{\circ}C$. Whereas, in the reaction of trimethylstannyldiethylamine with chloral, N,N-diethylformamide and trimethylstannyltrichloromethide were produced. The products from the reaction of N-ethylhexamethyldistannazane with phenylisothiocyanate were bis(trimethylstannyl) sulfide and N-ethyl-N'-phenylcarbodiimide.
실시간 데이타 처리 시스템의 성능 평가를 위한 시뮬레이션 모델
이일규(Il Kyu Lee),문송천(Song Chun Moon) 한국정보과학회 1990 정보과학회논문지 Vol.17 No.5
실시간 데이타 처리 시스템은 다음 두 가지의 중요한 요구 조건을 만족하여야 한다. 첫째로, 최고 부하에서도 각 입력 장치로부터 실시간으로 입력되는 데이타를 하나도 유실하지 않게 처리할 수 있어야 한다. 둘째로, 시스템 내의 모든 실시간 작업들에 대하여, 최악의 경우의 응답 시간들이 각각의 상한 요구 시간들보다 짧게 처리할 수 있어야 한다. 본 논문에서는 CPU와 disk를 사용하는 작업들이 존재하는 실시간 데이타 처리 시스템의 성능 평가를 할 수 있는 시뮬레이션 모델이 제안되었다. There are two major requirements in real-time data processing systems. The first one is to guarantee that the system can handle its peak processing load without losing any input real-time data from the devices. The second one is to guarantee that the worst case response times of all the real-time jobs in the system should be less than the required upper bound response times of them. In this thesis. a simulation model is proposed for performance evaluation of the real-time data processing systems in which each job uses not only CPU but also disk.
Triethylgermyldiphenylphosphine과 Phenylisocyanate의 반응
박성우,이일규,Sung Woo Park,Il Kyu Lee 대한화학회 1983 대한화학회지 Vol.27 No.1
Triethylgermyldiphenylphosphine과 phenylisocyanate를 1:10 mole 비로 ampoule 속에서 혼합하여 여러 온도에서 반응시켰다. 그 결과 $0^{\circ}C$에서는 phenylisocyanate의 고리화 2합체인 N, N-diphenyluretidine-2,4-dione만이, $20^{\circ}C$에서는 phenylisocyanate의 고리화 3합체인 triphenylisocyanurate가 함께 생성되었으며, $50^{\circ}C$에서는 위의 생성물 이외에 diphenylcarbodiimide가 생성되었다. 또한 $100^{\circ}C$이상에서는 2합체는 생성되지 않고, diphenylcarbodiimide와 1,3,5-triphenyl-2,4,6-tris(phenylimino) hexahydro-1,3,5-triazine이 주로 생성되었다. 그리고 Triethylgermyldiphenylphosphine은 상기 고리 화합물들의 생성에 촉매로 작용하였다. Triethylgermyldiphenylphosphine was reacted with phenylisocyanate at various temperatures for three days in sealed ampoules. At $0^{\circ}C$, only N, N-diphenyluretidine-2,4-dione, a cyclic dimer of phenylisocyanate (35%), was formed. But at $20^{\circ}C$, phenylisocyanutrate, a cyclic trimer of phenylisocyanate (30%), was formed along with the dimer. At $50^{\circ}C$, diphenylcarbodiimide (55%) was given together with the compounds described above. At the higher reaction temperatures than $100^{\circ}C$, instead of the dimer and trimer of phenylisocyanate, 1,3,5-triphenyl-2,4,6-tris(phenylimino) hexahydro-1,3,5-triazine, a cyclic trimer of diphenylcarbodiimide (30%) and diphenylcarbodiimide (70%) were mainly produced. Triethylgermyldiphenylphosphine appears to act as a catalyst for the formation of the above cyclic compounds.
Trimethylsilylamine 및 Trimethylstannylamine 과 Phenylisocyanate 와의 반응
김갑주,이일규,Ghap Ju Kim,Il Kyu Lee 대한화학회 1981 대한화학회지 Vol.25 No.2
Trimethyldiethylaminosilane, trimethylanilinosilane, trimethyldiethylaminostannane and trimethylanilinostannane were reacted with phenylisocyanate at various temepturares. All the reactions below $100^{circ}C$ gave only triphenylisocyanurate, but above $150^{circ}C$, diphenylcarbodiimide also was produced considerably. The reaction rate of anilinosilane was faster than that of aminosilane, but in the case of stannanes, the amino compound was more reactive. Trimethyldiethylaminosilane, trimethylanilinosilane, trimethyldiethylaminostannane 및 trimethylanilinostannane 을 phenylisocyanate와 20, 50, 100 및 $150^{circ}C$에서 각각 3일간 반응시켰다. 모든 경우, $100^{circ}C$ 이하에서는 triphenylisocyanurate만이, $150^{circ}C$ 이상에서는 triphenylisocyanurate와 함께 diphenylcarbodiimide도 상당량 생성되었다. 그 반응속도는 silane의 경우는 anilino 화합물이 diethylamino 화합물보다 빨랐으나, stannane의 경우에는 anilino 화합물이 diethylamino화합물보다 오히려 늦었다
