Esterification or etherification
of cellulose is the two main modification methods currently used to prepare cellulose derivatives.
Through the etherification
reaction between guar gum and 1-Bromododecane, the modified guar gum is synthesized.
Finally, absorption at 1000-1150 [cm.sup.-1] is related to C-O stretching of the ether groups present in the polyglycerol backbone  and etherification
reactions between polyglycerol and crosslinking agents.
process is mainly done to inhibit retrogradation .
of fatty acids of different fractions:
Wall panels fabricated from polyester resins reinforced with fiberglass so-called fiberglass reinforced plastic (FRP) are typically used in restaurants, kitchens, restrooms and other areas that require washable low-maintenance walls.Water, a by-product of etherification
reactions, is continuously removed, driving the reaction to completion.
The transformation of glycerol into fuel oxygenates has been developed using the etherification
of glycerol with alkenes or alcohols, the esterification of glycerol with acetic acid, and the ketalization of glycerol and ketones, from which polyglycerols, alkyl glycerol ethers, acetyl glycerols, and solketal were obtained, respectively [1, 2].
Aspirin derivatives 1-12 with aryl side chain bearing alkyl substituents were prepared from the reaction of acetoxybenzoyl isothiocyanate with a series of commercially available methyl and methoxy anilines and alkylated anilines prepared via Williamson etherification
. A general synthesis of 1-12 is depicted in Scheme 1.
The company specializes in a wide range of organic reaction technologies such as Amination, condensation, hydrogenation; Amidation, dehydrogenation & Mannich Reaction; Alkylation, diazotization & nitration; Bromination, esterifiction & oxidation; Catalytic hydrogenation, etherification
& reduction; Chlorination & hydrogenation.
It is also used in the etherification
of wood, purification of organosilicon compound mixtures, and disinfection of crude oil products.
