TL;DR: In this article, the critical water concentrations required for initiating precipitation of cellulose acetate from 20% solutions in acetone, dioxane, acetic acid, triethyl phosphate (TEP), dimethyl formamide (DMF) and dimethyl sulfoxide (DMSO) have been determined.

TL;DR: In this article, the effects of molecular structure on the catalytic behavior of bio-oil components in the steam-reforming reactions were presented, showing that an increased number of hydroxyl groups suppressed the generation of CH4 while promoting the production of CO and coke deposits.
Abstract: This paper presents the effects of molecular structure on the catalytic behavior of bio-oil components in the steam-re-forming reactions. Methanol, ethanol, 1-propanol, butanol, 2-propanol, 1,2-propanediol, glycerol, propionaldehyde, acetone, and propionic acid were used as model compounds. Steam re-forming of the alcohols with a long carbon chain was relatively difficult and yielded large amounts of CH4 and coke deposits. An increased number of hydroxyl groups in the alcohols suppressed the generation of CH4 while promoting the production of CO and coke deposits. Furthermore, the location of the hydroxyl group also impacted both the product distribution and carbon deposition in the re-forming process. The type of functional group significantly affected steam re-forming as well. Alcohol steam re-forming tended to produce a significant amount of CH4, while aldehyde (propionaldehyde) steam re-forming produced only small amounts of CH4 and other organic byproducts. Severe coke deposition was encountered in t...

TL;DR: It was found that whilst acetonitrile provided the highest column efficiencies and lowest detection limits of the solvents studied, acetone also performed well and could be used to resolve the same number of analytes as was possible with aconetitrile.
