Liquefaction and product identification of corn bran (CB) in phenol

Abstract

The liquefaction of corn bran (CB) was successfully conducted by using three different liquefaction conditions. Among them, catalyzed liquefaction at high pressure and temperature (180–220°C) using phenol was the most effective for the liquefaction of CB. Both the phenol/CB ratio and the catalyst content affected the extent of the liquefaction. The decomposed components of CB did not show high reactivity toward phenol when liquefied without a catalyst. Thermal‐flow properties of the phenolated CB and flexural properties of the phenolated CB‐based moldings were influenced by the amount of combined phenol and were comparable to those of the commercial novolak or phenolated wood. The effect of molding time and filler content on the flexural properties is also presented. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 78: 311–318, 2000

Glucose esters as biobased PVC plasticizers

“…It should, thus, be possible to decrease the cost of glucose and utilize it in industrial scale without consuming food resources. Polyols produced from wood flour cellulose [22], corn bran [23] and waste paper [24] have already been utilized to synthesize different polymers, mainly thermosets.…”

Biodegradability and Risk Assessment of Biomass-based Polymeric Materials

“…The obtained liquefied products were directly used to prepare polyurethane foam by reaction with diphenylmethane diisocyanate in the presence of catalyst, silicone surfactant, and water. Thermosetting moldings were prepared by hot-pressing the mixture of phenolated wood (37.7%), wood flour filler (49.5%), hexamine (9.4%), Ca(OH)2 (2.4%), and Zn stearate (1%) (Lee et al 2000b).…”

Metal Ion‐Catalyzed Hydrothermal Liquefaction of Calcium Lignosulfonate in Subcritical Water

“…These phenolic compounds from liquid products can be used as an important source of chemical intermediates. Numerous studies reported on the usage of the liquefied product from lignin to prepare phenol‐formaldehyde resin and polyurethane resin , . The incompletely carbonized solid product, i.e., hydrochar, from hydrothermal carbonization is also a kind of high‐available carbon source, which can be used as high‐energy solid fuel, precursor for preparation of activated carbon or carbon black, adsorbent, soil conditioner, etc.…”
