The result showed that 3 mL modifier was enough for the etherification

and crosslinking on the functional properties of corn," Wuxi Qinggongye Xueyuan Xuebao, vol.
products were analyzed using gas chromatography (GC), Agilent model 7890A, which was equipped with a DB-624 column (60 m, 0.25 mm, and 1.4 [micro]m), and a mass spectrometric detector (MS), Agilent model 5975C.
After hot press, the peaks weakened such as the groups of lignin at 110-160 ppm, C3/C5 of etherification
S-lignin at 153.0 ppm and 152.3 ppm, Ar of lignin at 122.0 ppm.
acid, alkanol, alkaline, esterification and etherification
developed an improved synthesis using an insoluble modified amine-functionalized anion exchange resin as the etherification
The use of modified montmorillonite, such as [Zr.sup.4+]-montmorillonite as a catalyst for esterification of carboxylic acids with alcohols ; and [Al.sup.3+]-montmorillonite as a catalyst for etherification
of [Me.sub.2]CHOH to [([Me.sub.2]CH).sub.2]O  have also been reported.
Hence, based on the variety of functional groups, etherification
, esterification, alkylation, hydroxyalkylation, graft copolymerization crosslinking, oxidation has been conducted to produce a series of products with many practical applications (Muzaffar et al., 2004).
Industrial applications of the technology include esterification systems such as methyl acetate (Agreda and Partin, 1984) and etherification
systems such as MTBE (Smith, 1994), ETBE (Thiel et al., 1997) and TAME (Hickey and Adams, 1994).
In addition, the etherification
of the 2-OH of (4) with an alkyl rest to give the novel pentacarbazole bicyclomahanimbiline (11) gave an increased activity of 55% and 51% at 24 and 48 h, respectively, of (11) (Table 1).
Jerome has prepared and successfully tested silica- and polymer-supported amine catalysts for the esterification and etherification
of sugars, leading to biodegradable emulsifiers.
The etherified forms of FA and PCA were highly correlated within the NDF fraction, suggesting some degree of generality in the etherification
