Acetone, butanol and ethanol (ABE) mixture separation from dilute aqueous fermentation products is an important process for the biofuel industry. Here, we present a novel approach for ABE recovery using microwave induced membrane distillation (MD). Carbon nanotubes (CNTs) and …
The lower critical solution temperature (LCST) of poly-N-isopropylacrylamide (p-NIPAM) diminishes when a small volume of acetone is added to the aqueous polymer solution, and then increases for further additions, producing a minimum at a certain acetone concentration. Here this behavior is observed through t Celebrating recent chemical science in Mexico
2005-03-26. Geranyl acetone is a monoterpene ketone in which an (E)-geranyl group is bonded to one of the alpha-methyls of acetone. It is a component of essential oils from various plants including Nelumbo nucifera. It has a role as a flavouring agent, a fragrance, a volatile oil … To a 100 mL flask equipped a large stir bar was added the 3-chloro-1-propanol (4.73 g, 0.050 mol) and acetone (50 mL, 1 M in the alcohol).
USE: Acetyl acetone is an important commercial chemical. It is used in many industrial processes as a lubricant additive, and to make colors, paints, varnishes, resins, inks, dyes, drugs and other chemicals. This sample has a selectivity to acetone approaching 98.5%, which is higher than those for all the previously reported materials, including titania-based materials. 15,44–52 Together with the outstanding activity presented by the composite samples, these results indicated that the B/g-C 3 N 4 composite is a highly active and selective material. The unconventional photoluminescence of sulfonated acetone–formaldehyde (SAF) and acetone–formaldehyde (AF) condensates are uncovered and studied in this work. Their fluorescence had been ignored although they were developed and commercialized as water reducing agents in the concrete industry decades ago.

Acetone (systematically named 2-propanone) is the organic compound with the formula (CH 3) 2 CO. It is a colorless, volatile, flammable liquid, and is the simplest ketone. Acetone is miscible with water and serves as an important solvent in its own right, typically for cleaning purposes in the laboratory.
