分子構造と標準沸点の関係
米澤節子、小渕茂寿、福地賢治、荒井康彦
要旨
An effective parameter, which can represent molecular structures, is desired to distinguish isomers. In a series of our studies, the normal boiling points are found to be useful to distinguish isomers. In this study, a branching ratio is introduced to represent molecular structures and the relationship between the branching ratios and the normal boiling points for hydrocarbons and alcohols is discussed. It is noted that the experimental normal boiling points seem to be more successful to represent the molecular structure differences and therefore to distinguish isomers.

気液平衡の相関と推算
小渕茂寿、米澤節子、福地賢治、荒井康彦
要旨
The definition of technical words “correlation” and “prediction” in the vapor-liquid equilibrium (VLE) calculation have been considered. “Correlation” should be used when VLE is calculated by using the experimental VLE data of a mixture concerned. Namely, this means the evaluation of the model parameters of an activity coefficient equation from experimental VLE data. On the other hand, “prediction” is acceptable when VLE can be obtained by calculation, with no VLE data of a mixture concerned, based on the knowledge of molecular structures and the pure component properties of constituent pure components. As a useful prediction method, UNIFAC has been widely adopted. The performances of UNIFAC and GC-W proposed by the present study are compared and discussed in the prediction of VLE for various binary mixtures consisting of non-polar and polar components.

気液平衡推算における GC-W の異種分子間相互作用パラメータ
小渕茂寿、高倉 啓、米澤節子、福地賢治、荒井康彦
要旨
In a series of our studies, GC-W (Group-Contribution method based Wilson equation) has been successfully proposed. It has been ascertained that GC-W is useful to correlate VLE (Vapor-Liquid Equilibria) with the interaction parameters ε12 and ε21 between unlike molecules. Further, the empirical equations have been developed to estimate ε12 and ε21 by using solubility parameters and normal boiling points of pure components. In this study, the characteristics of the interaction parameters ε12 and ε21 between unlike molecules have been considered and discussed for various specified binary mixtures.

災害支援物資管理システムの開発
瀧本浩一、壬生祐二
要旨
In 2011,Many people lost their houses and evacuated by tsunami after Tohoku-Pacific Ocean Earthquake. At this disaster, enormous relief materials have been sent to many disaster-stricken region. However, there are many problems about relief materials such as mismatch of the relationship between supply and the demand.
In this study, the author developed the database contents for management of relief materials. The relief package was also normalized to this size of the box when local governments send relief supplies to disaster areas governments.
