One of the most prominent papers to come from the Aspinall group, published with George Zweifel in 1957, reported on the selective tosylation of the 2,3-diols of methyl 4,6-O-benzyl idene-a-D-mannopyranoside (with axial and equatorial hydroxyl groups, respectively, at C-2 and C-3), and 1,6-anhydro-/i-D-mannopyranose (with a confor-mationally inverted pyranose chair, and therefore with equatorial and axial hydroxyl groups, respectively, at C-2 and C-3). In each case the equatorial hydroxyl group was esterified preferentially, consistent with the Barton/Cookson generalization,...

In 1898, George Barton patented a new process where molten lead was rapidly stirred and atomised into small droplets, which were then carried away and oxidised by a humidified air stream drawn through die pot. The resulting oxide was passed through a series of cyclone classifiers where the larger particles were separated and returned back to the reaction pot for further processing, while the fine powder was collected in silos (drums or hoppers). 

In 1898, George V. Barton proposed a method that made the production process of lead oxide considerably faster and easier. This method yields partially oxidized lead powder (leady oxide) which ensures high battery performance.

Sodium 0-ethyl xanthate in acetone added with stirring at —35° during 30 min. to phenacetyl chloride in the same solvent, after 1 hr. allowed to warm to room temp. 0-ethyl S-phenacetyl xanthate (Y 97%) in refluxing dioxane irradiated 3 hrs. with a Hg-arc lamp, and the resulting S-benzyl 0-ethyl xanthate refluxed 1 hr. in 1 9 aq. ale. 1 N NaOH a-toluenethiol (Y 96%). The acyl xanthates are smoothly converted into acyl and xanthate radicals. The former are de-carbonylated and recombine with the xanthate radicals. F. e. and limitations s. D. H. R. Barton, M. V.
