Details of the depolymerization, solvent separations, and product analyses were described previously (3, 4). Molecular weights of the benzene-, methanol-, and phenol-soluble fractions were determined cryoscopically using sulfolane as the solvent (li).

Martin B. Neuworth The molecular weights of the soluble fractions from our work were determined cryoscopically in sulfolane. Values of the order 300-700 were obtained. Using phenol solubility as a criterion of degradation limits the upper molecular weight to values below 1000.

Vomicidine is phenolic, soluble in alkali, and capable of the ready oxidative destruction typical of o-aminophenols the fact that vomicine itself appears not to be phenolic, on the other hand (not acylatable or soluble in alkali no ferric chloride test), has been ascribed to a masking of the hydroxyl by internal attack on the lactam carbonyl (CIX) (336). Another explanation is that the hydroxyl is just very strongly... 

By means of this technique, it is possible to produce phenol-soluble material amounting to as much as 75% w/w of the starting coal (lignite 70% carbon) on the other hand, a low-volatile bituminous coal (89% carbon) may only afford as little as 9% w/w phenol-soluble material. The molecular weights of the phenol-soluble products usually fall into the range 350-1050. Coal depolymerization is also reputed to occur when the coal is treated with an iron-based catalyst in the presence of hydrogen (Wang et al., 1992).

The solvent extraction is the most used method for phenolic compoimds obtainment from plant tissue. The main factor is the phenolics solubility, which depends on its chemical structure. Plant materials may contain different concentrations of phenolic acids, phenylpropanoids, anthocyanins and tannins. It is possible to occur interactions between phenolics and other plant components, such as carbohydrates and proteins which form complexes responsible for insolubility. Besides that, the polarity of solvent affects the solubility and therefore, it is eonsidered difficult to develop a extraction method suitable for all plant phenolics [18]. 

The phenol-soluble envelope fraction of Escherichia coli has been shown to consist of at least three distinct glycoproteins one of them has an appreciable rate of turnover and is thought to be involved in the transfer of carbohydrates in the envelope. Analysis of the outer- and inner-membrane glycoproteins showed that they are not identical. The principal envelope protein of Halobacterium salinarium is also a glycoprotein of molecular weight 1.94 x 10 . ...
