the present invention relates to a process for the production of the lactide (ld) from l-lactic acid water. the aqueous lactic acid to the current needs, includes a slurry of one or more of the following: lactic acid, a dimer of lactic acid and lactic acid trimer, possibly in the ...
Lactic acid adsorption and dehydration toward acrylic acid processes have been studied by means of density functional theory (DFT) calculations on 011, 1 0 1 mathContainer Loading Mathjax , and 1 1 1 mathContainer Loading Mathjax monoclinic zirconia surfaces. Lactic acid presents two function ...
#SkinSchool: Everything you need to know about lactic acid, plus the best lactic acid-based skincare products to try now.
Method for producing lactide directly from lactic acid and a catalyst used thereinThe present invention provides a method for directly producing lactide by subjecting lactic acid to a dehydration reaction in the presence of a catalyst comprising a tin compound, preferably, a tin (IV) compound, ...
A process for producing an acidic dehydration catalyst to convert lactic acid to acrylic acid. The process comprises impregnating an inert metal oxide carrier with a phosphate salt and buffering the impregnated carrier with a base to a pH sufficient to provide the effective dehydration catalyst. Inve...
