Five ionic liquids based on a quaternary ammonium core substituted with a D-glucose moiety and alkyl chains of varying length were synthesized as prospective phase-transfer catalysts. The catalytic activity of the obtained ionic liquids was tested in the dehydrochlorination of 3,4-dichloro-1-butene to chloroprene. The reaction proceeded in a two-phase system in the presence of an aqueous solution of sodium hydroxide. The results showed that the longer the alkyl chain in the cation, the higher the activity of the ionic liquid as a phase-transfer catalyst. The tested ionic liquids gave an easily recyclable system compared to classical phase-transfer catalysts that were soluble in the reaction system, with no leaching observed over five cycles (chloroprene yield >99%). The cytotoxicity and biodegradability of a series of synthesized ionic liquids based on D-glucose were determined so that a preliminary hazard assessment could be undertaken. Solvent-free synthesis of chloroprene in the presence of biodegradable surface-active D-glucose-based quaternary ammonium ionic liquids This study involved multiple reactions and reactants, such as (2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3Product Details of 604-69-3).
(2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Product Details of 604-69-3
