Furfural (C 5 H 4 O 2, furan-2-carbaldehyde, 2-furaldehyde) is a renewable platform chemical with a heteroaromatic furan ring and an aldehyde functional group. It is produced industrially by dehydration of hemicellulose components (pentose) of the lignocellulosic biomass.
From furfural aldoxime (with thionyl chloride-benzotriazole, triphenylphosphine-iodine reagents, or heating in DMSO) and furoic acid amide (flash vacuum pyrolysis). Applications. 2-Furonitrile currently has no major applications but it is used as an intermediate in pharmaceutical and fine chemical synthesis.
Furfural is an aldehyde that is furan with the hydrogen at position 2 substituted by a formyl group. It has a role as a Maillard reaction product and a metabolite. It is a member of furans and an aldehyde.
The market accounted for $663 million in the year 2015, and is expected to grow at a CAGR of 11.6% to reach $1,434 million by 2022. Increase in awareness regarding the renewable alternatives has compelled manufacturers to increase production of biomass-based chemicals such as furfural to produce additives, resins, and fuels to replace the non-renewable resources such as petrochemicals.

Furfural is a colorless, oily liquid that turns reddish brown on exposure to light and air. It is used in making chemicals, as a solvent in petroleum refining, a fungicide, and a weed killer. REASON FOR CITATION * Furfural is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, HHAG, NFPA, and EPA.
luka Chemical Corp. Davos Chemical Corp. ICN Biochemicals. Use Pattern: HMF is used in the synthesis of dialdehydes, glycols, ethers, amino alcohols and acetals. As an aqueous acid it catalyzes ring opening (Budavari, 1989). Generation of HMF (from starch) in the presence of phenol is used to produce phenol/furfural novolak-type resins (Brode ...
Opinion on furfural _____ 5 1. BACKGROUND Furfural (CAS No 98-01-1 and EC No 202-627-7) has a widespread use in cosmetic products as a perfumery ingredient. Furfural is classified as a CMR carcinogen cat. 2 under the EC Regulation No 1272/2008. The first scientific opinion (SCCNFP/0822/04) on furfural was adopted by the SCCNFP during
Due to the polar nature of furfural, it will dissolve quite readily and form solutions with a variety of polar organic solvents like methanol, ethanol, chloroform, and dimethyl sulfoxide (DMSO).
Furfural (C 4 H 3 O-CHO), also called 2-furaldehyde, best known member of the furan family and the source of the other technically important furans. It is a colourless liquid (boiling point 161.7 °C; specific gravity 1.1598) subject to darkening on exposure to air.
zation in the production of several bioproducts such as furfural, which can be used in diverse applications and used in the pro duction of other important chemicals. Therefore, this article has the purpose of analyzing applic a-tions and different production methods for furfural from lignocellulosic biomass. A review about the chemical
In addition, furfural is a common industrial solvent and an intermediate for preparation of fine-chemical products, resins/plastics, and biofuel (Climent et al. 2011; Li et al. 2014). Furfural is conventionally produced by hydrolysis of a variety of biomass sources including almond shell, sugarcane, and corn with the aid of liquid acid ...
compounds to fine chemicals and fuels [11,7,12-13,9]. Furfural (FF), a lignocellulose derivative, is a promising platform chemical which can be used as an adhesive, fungicide, nematocide and extracting agent [14-17,8,18]. Additionally, it can be transformed into value-added chemicals and fuel components such as
Studies in humans and animals show that furfural is readily absorbed and is excreted in the urine. The American Conference of Governmental Industrial Hygienist's (ACGIH) occupational standard for furfural, or Threshold Limit Value (TLV) is 2 ppm with a "Skin" notation for concerns for vapor irritation of skin and mucous membranes.
Furfural, a sister chemical to the increasingly popular hydroxymethylfurfural or HMF molecule, is regaining attention as a biobased alternative for the production of everything from antacids and fertilizers to plastics and paints.

Issued December 1, 1985 Temperature Classes of Electrical Insulators Shimizu Ohta 1. Introduction In early times, the temperature classes of electric insulators were simply divided into natural organics, inorganics, and combinations thereof. In the late 1930s, the types of synthetic resins became diverse and their production
The name furfural comes from the Latin word furfur, meaning bran, referring to its usual source. Furfural is only derived from lignocellulosic biomass, i.e. its origin is non-food or non-coal/oil based. Aside from ethanol, acetic acid and sugar it is one of the oldest renewable chemicals. It is also found in many processed foods and beverages.
The permeation characteristics of mixtures can deviate considerably from the permeation behavior of the individual chemicals. Chemical warfare agents (Lewisite, Sarin, Soman, Sulfur Mustard, Tabun and VX Nerve Agent) have been tested at 22°C and 50% relative humidity per military standard MIL-STD-282.
