Volume 1, Issue 1 , January 2014, , Pages 33-41

https://doi.org/10.22063/poj.2014.904

Abstract
  Primary MgCl2.3.3EtOH adduct (PCT1) was prepared by melt quenching method and then submitted into a programmed thermal dealcoholation project using a fluidized bed reactor. During thermal dealcoholation program, different MgCl2.nEtOH support samples with n= 3.0, 2.7, 2.4, and 2.1 were selected and named ...  Read More
