The dehydration behavior and non-isothermal dehydration kinetics of donepezil hydrochloride monohydrate

Tiantian LIU, Yuanyuan RAN, Bochao WANG, Weibing DONG, Songgu WU, Junbo GONG

Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 1, Pages 55-63 doi: 10.1007/s11705-013-1352-3

Abstract: Powders of donepezil hydrochloride monohydrate (Form I) underwent isomorphic dehydration, losing 3% wBelow 10% RH, additional dehydration occurred in conjunction with a reversible phase transition betweenForm I showed the characteristics of the channel hydrate, whose non-isothermal dehydration behavior proceedsThe dehydration kinetics was achieved from the TG-DTG curves by both the Achar method and the Coats-RedfernThe dynamic dehydration processes for steps 1 and 2 were best expressed by the Zhuralev-Lesokin-Tempelman

Investigations on dehydration processes of trisodium citrate hydrates

Junyan GAO, Yanlei WANG, Hongxun HAO

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 3, Pages 276-281 doi: 10.1007/s11705-012-1206-4

Abstract: The dehydration processes of trisodium citrate (Na C H O ) hydrates were investigated using thermogravimetryIt was found that the temperature of dehydration of trisodium citrate dihydrate was at 430.99 K.For trisodium citrate pentahydrate, there is a two-step dehydration process and the endothermal peaksDuring the first step of dehydration process, the structure of trisodium citrate pentahydrate changeddehydration mechanisms of the two hydrates were different.

Study of zeolite membranes for pervaporation dehydration and their applications

Gu Xuehong,Xu Nanping

Strategic Study of CAE 2014, Volume 16, Issue 12, Pages 52-58

Abstract:

A seeding method by rubbing-dipcoating and induction with ball-milled seeds was developed to synthesize NaA zeolite membrane. The synthesis approach could improve the rate of qualified membranes and reduce the synthesis time efficiently，which is suitable for large-scale production of zeolite membranes. Mass transfer mechanism of organic solvent and water in a zeolite membrane was investigated with molecular simulation method. The stability of NaA zeolite membranes in hydrothermal，acid-base and salty environments was systematically studied. A pretreatment method was then proposed and industrial pervaporation plants were built up，which have been operated steadily for long term.

Micro-sized hydrothermal carbon supporting metal oxide nanoparticles as efficient catalyst for mono-dehydration

Cheng PAN, Chao FAN, Wanqin WANG, Teng LONG, Benhua HUANG, Donghua ZHANG, Peigen SU, Aqun ZHENG, Yang SUN

Frontiers in Energy 2022, Volume 16, Issue 5, Pages 822-839 doi: 10.1007/s11708-020-0677-0

Abstract: Most known catalytic dehydration of sugar alcohols such as D-sorbitol and D-mannitol can only produceMoreover, both di- and mono-dehydration demand a high temperature (150°C or higher), which deserves furtherOn the other hand, high mono-dehydration selectivity is obtained for both sugar alcohols by using allThe origin of mono-dehydration selectivity and role of carbon component in catalysis are discussed inThis study provides an efficient, mild, eco-friendly, and cost-effective system for mono-dehydration
