Benzyl alcohol 290 INDEX

In 1899 Thoms isolated an alcohol from Peru balsam oil, which he termed peruviol. This body was stated to have powerful antiseptic properties, but has not been further investigated until Schimmel Co. took up the subject. The oil after saponification was fractionated, and after benzyl alcohol had distilled over, a light oil with characteristic balsamic odour passed over. It boiled at 125° to 127° at 4 mm., and had a specific gravity 0 8987, optical rotation -1- 12° 22, and refractive index 1-48982. This body appeared to be identical with Hesse s nerolidol, whilst in physical and chemical properties it closely resembles peruviol. The characters of the various preparations were as follows —... 

A number of researchers have also used a proposed ASTM test mixture, benzaldehyde, acetophenone, methyl benzoate, dimethyl terphtha-late, benzyl alcohol, and benzene to demonstrate separation on a column [98]. However the first four compounds are from the same interaction group and should behave in the same way on changing conditions. The first three have almost constant indices (respectively 760, 800, and 890) so that in effect they create an index scale with constant differences against which the last two compounds can be compared [96,99]. 

A further aid in the location of the solvents and their exact specification is the Chemical Abstracts (CAS) Registry Number, shown in the second column. The Chemical Abstracts name may be the same as the commonly used one or may differ from it considerably, so that it is not always easy to find the solvents in these Chemical Substance Indexes of the Chemical Abstracts. Eor instance, benzene, methyl is a fairly transparent name for toluene, and methanol, phenyl a slightly less one for benzyl alcohol, but one has to become familiar with the systematics of Chemical Abstracts nomenclature in order to search for diethyl ether or any other more complicated compound. It is expected that with all this information available in table Al the solvents listed are definitely specified and readily found in the Abstracts and other compilation of information and data.

A1 (8.103) and Zn (8.104 and 8.105) complexes are efficient initiators for l-LACTIDE ring-opening polymerization in the presence of benzyl alcohol, and polymerization reactions take place in an immortal manner, that is, their polydisper-sity index (PDI) is almost 1 (PDI=1.02,MW= 13,000-14,000) [147].Bis(phosphino) carbazole (PNP-carbazolide) rare-earth metal bis(alkyl) complexes (8.106) initiated... 

At the end of the transformation, acetic anhydride in excess is hydrolyzed in acetic acid, which is directly titrated in the reaction medium with a sodium hydroxide solution in the presence of phenolphthalein. The same operations are realized with a blank in which there is no hydroxylated derivative, all the other experimental conditions being the same as in the assay. The difference between both volumes added gives the number of moles of acetic acid used for the esterification. The in pyridine acetylation index is of great interest in the analysis of essential vegetable oils, fats, and numerous pharmaceutical compounds, including, for instance, the determinations of cetylic and benzylic alcohols. The propionyl index is based on the same principle, but all of the operations are performed in a nonaqueous medium. 

To avoid autoinitiation, the bulk polymerization was carried out at 65 °C. When DBU was used as a catalyst in the presence of benzyl alcohol, TMC was polymerized within minutes, yielding polymers with controlled molecular weight and small dyspersity index (1.09-1.15). To demonstrate the living nature of the polymerization carried out under bulk conditions, the chain extension experiment was conducted. Resultant polymer growth proceeded in a linear fashion. It was demonstrated that the intermediate chains can be employed for further growth, by the addition of more...
