Furfuryl alcohol resins contain a broad spectrum of compounds. The distribution of these compounds in a given resin varies with the manufacturing conditions. A resin containing a high proportion of low molecular weight constituents has been prepared and separated into fractions.
Furfuryl Alcohol is an effective viscosity reducer for epoxy resins. Furfuryl Alcohol is also used as a chemical building block for pharmaceutical drug synthesis, especially Ranitidine which goes into formulation of anti-ulcer drug.

Basis for original (SCP) IDLH: The chosen IDLH is based on the rat 4-hour LC 50 of 233 ppm of a furfuryl alcohol, hydrazine, and aniline mixture [Jacobson et al. 1958]. Also, Deichmann and Gerarde  stated that 8% mortality resulted from a 6-hour exposure of rats to 47 ppm furfuryl alcohol and ...
Proposition 65 vs. Processed Food Companies - A New (Costly) Thorn in Your Side. The addition of furfuryl alcohol, a natural by-product of thermal food processing, to the Proposition 65 list will likely result in added litigation risks for food/beverage manufacturers selling products in California.
Furfuryl alcohol, also known as furanmethanol, 2-furancar-binol, 2-hydroxymethylfuran, and furfural alcohol, is most commonly used in foundry operations as a binding agent and as a corrosion inhibitor. Properties such as low viscosity, high reactivity, and excellent solvent characteristics make it valuable to a variety of industries.
Furfuryl alcohol Results in the Carcinogenic Potency Database. The Carcinogenic Potency Database (CPDB) is a unique and widely used international resource of the results of 6540 chronic, long-term animal cancer tests on 1547 chemicals.

Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence, [Wischmeyer(1969)]. An explosion occurred in a laboratory when cyanoacetic acid was reacted with furfuryl alcohol in an attempt to form the ester, furfuryl cyanoacetate.
Furfuryl alcohol, produced by Silvateam, is a clear colorless organic liquid when pure, but becomes amber upon prolonged exposure to light and air. Furfuryl alcohol, produced in Argentina, is produced using a catalytic hydrogenation process at high pressure, starting from furfural. Furfuryl alcohol has a purity of 98.5%.

Furfuryl alcohol is an organic compound containing a furan substituted with a hydroxymethyl group. It is a colorless liquid, but aged samples appear amber. It possesses a faint odor of burning and a bitter taste. It is miscible with but unstable in water. It is soluble in common organic solvents.
Because of its Near Ubiquity in Food, California Must Set a Realistic Safe Harbor Level for Furfuryl Alcohol October 1, 2015 - 5 minutes read. California has extended the comment period for the common food ingredient, furfuryl alcohol, for listing as a carcinogen under Proposition 65 (Prop. 65); comments are now due at the end of September.
An Incisive, In-depth Analysis on the Furfuryl Alcohol Market. This study offers a comprehensive, 360 degree analysis on the Furfuryl Alcohol market, bringing to fore insights that can help stakeholders identify the opportunities as well as challenges.
(US EPA) that furfuryl alcohol causes cancer, and on the scientific evidence relied on by US EPA2. US EPA is designated as an authoritative body for purposes of listing chemicals as causing cancer pursuant to Title 27, Cal. Code of Regulations, section 253063. Furfuryl alcohol will therefore be added to the Proposition 65 list as a chemical
Furfuryl alcohol is the major ingredient in FURAN foundry binders . The flexibility of furfuryl alcohol as a binder base is enormous. Today furfuryl alcohol is used in binders for HOT-BOX, WARM BOX and gas hardened processes as well as in the traditional FURAN-NO-BAKE system. Furan NO-BAKE (FNB) was introduced in 1958. It is suitable for ...
Furfuryl alcohol is a colorless, liquid that becomes a brown/amber color over time as it is exposed to light and air. It has a faint burning odor and a bitter taste. It's soluble in alcohol, chloroform, benzene, and water. Furfuryl alcohol can be used as a wetting agent for resins, cores, and molds. It can also be used for flavoring.
Determination of free furfuryl alcohol in foundry resins by chromatographic techniques Article (PDF Available) in Analytica Chimica Acta 537(1) · April 2005 with 967 Reads How we measure 'reads'
Currently, furfuryl alcohol is used mainly in binders for the traditional furan no-bake system and in smaller quantities in furan hot-box, warm-box, and gas-hardened processes. In its main application, the foundry business, furfuryl alcohol competes primarily with phenol, the feedstock for phenolic resins.
The chemical processes involved in the reactions between novolac resins, furfuryl alcohol (FA), and hexamethylenetetramine (HMTA) have been studied by solid-state NMR spectroscopy. A highly cross-linked homogeneous network which incorporates both novolac and furan entities is formed.
A wide variety of furfuryl alcohol options are available to you, such as industrial grade, food grade, and agriculture grade. There are 448 furfuryl alcohol suppliers, mainly located in Asia. The top supplying countries or regions are China, India, and Philippines, which supply 97%, 1%, and 1% of furfuryl alcohol respectively.
Our chemical platform finds it's origins in the conversion of hemicellulose to furfural. Furfural, a CO neutral chemical is converted into furfuryl alcohol. This renewable alcohol is subsequently polymerized to polyfurfuryl alcohol (PFA or Poly-FA). Poly-FA is the basis of our thermoset resin systems: BioRez - Furolite.
Substitute materials of furfuryl alcohol in furan resin used for foundry and their technical properties Male, born in 1970, senior engineer and doctoral candidate.

The present work involves the optimization of RVC manufacture by monitoring the polyurethane (PU) foam impregnation with furfuryl alcohol resin with different viscosity values, which were obtained by dilution of the resin with different amounts of furfuryl alcohol. The resin samples used in the PU impregnation were characterized by thermal and ...
detection (LC–UV), were used to determine furfuryl alcohol in several kinds of foundry resins, after application of an optimised extraction procedure. The GC method developed gave feasibility that did not depend on resin kind. Analysis by LC was suitable just for furanic resins.
