The effects of conditions of moulding on the surface resistivity in the range of 106 to 1010 ohms/square of a carbon-fibre/poly(ether sulphone) short-fibre composite

Autor: C. L. Schutte, R. O. Hutchins

Publikováno v: Polymer. 34:476-480

The logarithm of the surface resistivity, log(SR), for a poly(ether sulphone)/carbon-fibre composite ranged between 6.23 and 10.66, depending on the conditions of moulding. The statistically significant variables were: the injection pressure, PI; the

A reinvestigation of the chemistry of pinol

Autor: J. H. Thorstenson, R. O. Hutchins, Joseph Wolinsky

Publikováno v: Tetrahedron. 27:753-765

The addition of bromine to pinol is shown to give 6,7-diendo-dibromocineole (6) which on treatment with hydrogen bromide is converted into “pinol tribromide” which is now formulated as 2,6-dibromo-4-(α-bromoisopropyl)-1-methyl-1-cyclohexanol (7)

Convenient and stereoselective dithiol synthesis

Autor: R. O. Hutchins, S. Smith, V. S. Rao, E. L. Eliel

Publikováno v: The Journal of Organic Chemistry. 40:524-526

Aus den Dihalogen- oder Disulfonyloxy-Derivaten (I) entstehen mit Natriumsulfid cyclische und oligomere Disulfide (II) bzw. (III), die mit Lithiumalanat zu den Dimercaptanen (IV) reduziert werden.
