Disclosed herein is the catalytic dehydration of lactic acid to acrylic acid, which is characterized by a high conversion of lactic acid, a high selectivity for acrylic acid, a high yield of acrylic acid, and correspondingly low selectivity and molar yields for undesired by-products. This is ...
This report shows that complete control of the degree of alkali exchange is possible by controlling the pH strength, and that is possible to distinguish the selectivity of the cations themselves in the lactic acid (LA) dehydration reaction by excluding undesired active sites arising from excess salt...
lactic acid to acrylic acid might be an effective alternative way for acrylic acid production.This paper provides a review on the main approaches of acrylic acid production with particular focus on the current research situation for lactic acid dehydration methods,prospects for acrylic acid production ...
Lactic acid is then separated, purified, and dehydrated to acrylates via a competitive chemical process. Holmen discovered the vapor-phase conversion of lactic acid to acrylic acid using several kinds of salt catalysts for the first time [2]. In his study, the lactic acid solution was passed ...
Lunelli, Production and control of the acrylic acid ester synthesis through lactic acid fermentation [Ph.D. Study of Lactic Acid Thermal Behavior Using Thermoanalytical Techniques In the present study, the addition of molasses alone enhanced lactic acid fermentation, declining pH. Adding distiller's ...

46 The capacity of microorganisms for lactic acid fermentation can be ranked on the basis of their ability to ferment 0.5% raw potato starch in agar.2973 When starch is fermented, not only does it play a role as the source of lactic acid via glucose and pyruvic acid but it is also an ...
Reactive extrusion of poly(lactic acid) with styrene-acrylic-glycidil methacrylate 来自 ResearchGate 喜欢 0 阅读量: 22 作者:OS Perez,J Cailloux,E Franco-Urquiza,JJ Bou,ML Maspoch 摘要: In this paper are discussed the rheological changes observed in PLA by one-step reactive extrusion-calander...
This invention relates to catalytic dehydration of lactic acid derived from biological fermentation and its esters into acrylic acid and acrylic acid esters respectively. Disclosed in this invention are chemical catalysts suitable for industrial scale production of acrylic acid and acrylic acid esters. Thi...
