    Notes: Abstract The activity and enantioselectivity of Candida rugosa lipase were investigated in chiral solvents, (−)-, (+)- and racemic carvone, for the resolution of 2-chloro-propionic acid with n-butanol via esterification. The activity of the enzyme studied was about 50% higher in (−)-carvone than in (+)-carvone, however the enantioselectivity was similar.

    Notes: Summary Enantioselective esterification of 2-bromopropionic acid with n-butanol using Candida cylindracea lipase was carried out in n-pentane at various initial water contents. Reaction rate as well as enantioselectivity decreased at high water content. A heteroazeotropic distillation method was applicable to remove the excess water continuously and to work at the optimum reaction conditions.

    Description / Table of Contents: Abstract Исследован каменный образец из гор Токай (Венгрия), содержащий морденит, и каталитические свойства его различных форм, модифицированных химической обработкой, в процессе изомеризации н-гексана. Добавление Pt к катализатору приводит к резкому снижению скорости крекинга и скорости дезактивации, что приводит к катализатору с высокой селективностью к изомерам гексана.
    Notes: Abstract A mordenite-containing rock sample from the Tokaj Mountains (Hungary) and its various forms modified by chemical treatment have been tested for catalytic properties during isomerization of n-hexane. Addition of Pt to the catalyst leads to a sharp decrease in the rate of cracking and in the rate of deactivation and this results in a catalyst of high selectivity for hexane isomers.
