Teflon gloves

Because of their widespread use in the American workplace, butyl rubber, nitrile latex, neoprene latex, poly(vinyl alcohol), surgical rubber latex, and Viton elastomer were chosen for the present studies. The composite/bonded substances of this study were not in all cases presently available as commercial material for protective garments, but rather were chosen to determine their potential for resistance to solvent permeation. Likewise, Teflon gloves were included in these studies simply because they are commercially available.

Products in the reaction mixture were analyzed by infrared and nmr spectroscopy. IR spectra were obtained on a Perkin-Elmer 521 infrared spectrophotometer. The reaction mixture was first suction filtered through a fine porosity glass frit inside a glove box (Vacuum Atmosphere HE-43-2) under an argon atmosphere, and was placed in NaCl cells (International Crystals, Inc.) of path length 0.1 or 0.5 cm with Teflon stoppers. H nmr spectra... 

Benzophenone (2.0 g, 11 mmol) and sodium beads (0.6 g, 26 mmol) are loaded into a 100-mL Schlenk flask equipped with a Teflon coated stir bar in a glove box. Under an N2 atmosphere degassed THF, 60 mL, is added, and the solution is vigorously stirred for at least 1 h. The resulting solution of sodium benzophenone is deep blue or purple, and it must be protected from air by an N2 atmosphere. 

In the glove box, 8.1 g (34.0 mmol) of freshly amalgamated uranium turnings (see Section 55.A) are placed in an oven-dried, 250-mL, one-neck Schlenk reaction vessel, along with a 1-in. Teflon-coated magnetic stirring bar, and 200 mL of distilled, degassed pyridine. The reaction vessel is removed from... 

The useful potential window of the equimolar AlCl3-NaCl melt extends from about 2.2 to 0 V vs. the A1(III)/A1 couple in NaCl(satd) melt. Plambeck [30] summarizes the physical properties of the equimolar (mp = 151 °C) and 63-37 mol% eutectic melts. Pyrex cells are satisfactory for use with the AlCl3-NaCl melt. Teflon has also been used in these melts, but it slowly decomposes. Experimentation with the alkali metal chloroaluminates requires the use of an inert-atmosphere glove box or a gas-tight cell. 

Figure 17.11 Transmission spectroelectrochemistry cell designed for use with room-temperature haloaluminate melts and other moisture-reactive, corrosive liquids, (a) Auxiliary electrode and reference electrode compartments, (b) quartz cuvette containing the RVC-OTE, (c) brass clamping screw, (d) passageway between the separator and OTE compartment, (e) fritted glass separator, (f) A1 plate, (g) lower cell body (Teflon), (h) upper cell body (Teflon). This cell is normally used inside a glove box and is optically accessed with fiber optic waveguides. [From E. H. Ward and C. L. Hussey, Anal. Chem. 59 213 (1987), with permission.]...

The preparation of this extremely explosive material is reported, It once exploded spontaneously on isolation. It is recommended that no more than 100 mg be handled, using face-shields, leather aprons, Kevlar gloves and Teflon spatulas. Some pentaazidotellurate(IV) salts were also prepared a yellow oil probably the crude tetramethylammonium salt exploded on stirring [1], Tellurium tetraazide was reported by another group at much the same time, they also prepared a hexaazido-tellurate (2-) as the bis(tetraphenylphosphonium) salt [2],...
