3-ACETAMIDOPHENOL C화학적 특성, 용도, 생산

화학적 성질

off-white to tan or light grey crystals,

용도

analgesic

정의

ChEBI: A derivative of phenol which has an acetamido substituent located meta to the phenolic -OH group. It is a non-toxic regioisomer of paracetamol with analgesic properties, but has never been marketed as a drug.

일반 설명

Light gray solid.

공기와 물의 반응

Water insoluble.

반응 프로필

Phenols 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 Ka = 1.3 x 10^[-10]). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and 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. 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. Flammable gases are formed by the reaction of organic amides with strong reducing agents. Amides are very weak bases (weaker than water). Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

화재위험

Flash point data for 3-ACETAMIDOPHENOL are not available. 3-ACETAMIDOPHENOL is probably combustible.

Purification Methods

Recrystallise the phenol from water. The 3,5-dinitrobenzamide complex gives orange-yellow crystals from hot H2O and has m 212o. [Beilstein 13 H 415, 13 I 132, 13 II 213, 13 III 950, 13 IV 977.]
