CARBOFURAN PHENOL, Compounds in this group do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has pKa = 9.88). These materials are incompatible with strong reducing agents such as hydrides, nitrides, alkali metals, and inorganic sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases. Such heating may initiate polymerization of the organic compound. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). The reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid. Nitrated phenols often explode when heated. Many of them form metal salts that tend toward detonation by rather mild shock.

ALFALFA CONTAINING CARBOFURAN RESIDUES WAS ADMIN TO A COW. THESE RESIDUES WERE METABOLIZED AND EXCRETED AS SULFATES OF 3-KETO-7-PHENOL (65%), THE 7-PHENOL (9.4%) AND THE 3,7-DIOL (6.4%).

(14)C-CARBOFURAN WAS APPLIED TO SOLN IN WHICH THE ROOTS OF 3-4 YEAR OLD MUGHO PINE WERE IMMERSED. ... IN ADDN TO TWO UNIDENTIFIED COMPD, CARBOFURAN PHENOL AND LESSER AMOUNTS OF 3-HYDROXYFURAN AND 3-KETOCARBOFURAN PHENOL WERE PRESENT.

RATS WITH THEIR BILE DUCTS CANNULATED WERE GIVEN AN ORAL DOSE OF RING-LABELED CARBOFURAN; WITHIN 48 HR THEY HAD EXCRETED 28.5% OF THE DOSE IN THEIR BILE, 65.4% IN THEIR URINE, AND 0.4% IN THEIR FECES. ...THE RELEASED COMPD...INCLUDED...CARBOFURAN PHENOL...
