Acetins

The methods of analysis of the American Oil Chemists Society (AOCS) are the principal procedures followed in the United States and Canada and are official in commercial transactions. When the material is for human consumption or dmg use, it must meet the specifications of the USP (12). Commercial distilled grades of glycerol do not requite purification before analysis by the usual methods. The deterrnination of glycerol content by the periodate method (13), which replaced the acetin and dichromate methods previously used, is more accurate and more specific as well as simpler and more rapid. 

Acetins. The acetins are the mono-, di-, and triacetates of glycerol that form when glycerol is heated with acetic acid. Physical properties are shown in Table 4 they are all colorless.

A current example of the use of a polyester resin as a proplnt binder is the patd compn of Cohen and Scotoni (Ref 32b). In this formulation conventional polyester-olefinic copolymers are used (50,1) together with NG (42.5), tri-acetin (2.7), adiponitrile (2.7), PbO (0.5) and acetylsalicyKc acid (1.5%) to obtain 27 and 152mm caseless ammo...

During the year there were a number of reports in the press of deaths associated with phen-acetin. The Committee emphasised that the hazard was associated with the abuse of the drug (excessive doses taken over a long term) and reiterated that, consequently, no special action was necessary. Furthermore, because a drug (including phenacetin) could be marketed under different proprietary names, it could confuse a doctor. Therefore, the Committee decided that they would not consider an application by a manufacturer to market a new substance unless the applicant gave an assurance that an approved name had been obtained or applied for. 

The Commission and the CSM also made recommendations on the introduction of many other broad safety measures. These included the Phen-acetin Prohibition Order (SI 1974/1082), presentation of medicines in relation to child safety (SI 1975/2000), and declaration of alcohol in medicinal products on their package as active ingredient where this is likely to be pharmacologically active. Other labelling issues culminated in an Order (SI 1976/1726) that set out the standard particulars that must be shown on the containers and packaging of medicinal products. Consultations on other generally applicable warnings on the labels of certain medicines to protect children and to ensure that...

Another method of prepn of acetyl laurin is to treat triacetin (see under Acetins), in the presence of an alkaline catalyst with lauric acid to replace one of the acetyl groups. The AcOH produced by the reaction can be removed by azeotropic distn using sufficient hydrocarbon solvent to maintain the distn temp at ca 200°...
