Glasses mechanisms

A suspension of sodium amide2 (0.1 mole) in liquid ammonia is prepared in a 500-ml. three-necked, round-bottomed flask fitted with a West condenser, a ball and socket glass mechanical stirrer (Note 1), and a dropping funnel. In the preparation of this reagent a small piece of clean sodium metal is added to 350 ml. of commercial anhydrous liquid ammonia. After the appearance of a blue color, a few crystals of hydrated ferric nitrate are added, whereupon the blue color is discharged. The remainder of the 2.3 g. (0.1 mole) of sodium (Note 2) is then rapidly added as small pieces. After all the sodium has been converted to sodium amide (Note 3), a solution of 16.4 g. (0.1 mole) of ethyl phenyl-acetate (Note 4) in 35 ml. of anhydrous ethyl ether is added dropwise over a 2-minute period, and the mixture is stirred for 20 minutes. To the dark green suspension is added over an 8-minute period a solution of 18.5 g. (0.1 mole) of (2-bromo-...

The potassium salt of dimethyl sulfoxide can also be prepared in the following manner. In a 1-1. three-necked flask equipped with an all-glass mechanical stirrer, a 125-ml. dropping funnel containing 90 ml. of dry dimethyl sulfoxide (Note 1), and a Claisen distillation head and condenser is placed 425 ml. of dry 2-butyl alcohol (Note 1). The system is flushed with dry... 

Stanewsky There is one aspect of the Cry double knockout behaviour that has always puzzled me. It never looked to me that it was just masking, because they seem to anticipate the LD transition. This would fit perfectly with your assumption that it is an hour-glass mechanism. 

Silica powder was mechanically treated in a vibrational mill in an inert atmosphere at 300 or 77 K in a quartz vessel with milling balls made from quartz glass. Mechanical treatment of silica [9,10] is accompanied by the... 

A 250-ml, three-necked, round-bottomed flask (to which is attached at the bottom a coarse-sintered-glass frit, a Teflon stopcock, and a standard-taper male joint) is equipped with a 100-ml pressure-equalizing addition funnel, a reflux condenser, and a Tru-bore glass mechanical stirrer with a Teflon blade. The system is flushed with dry nitrogen via a gas inlet in the addition funnel and a gas outlet in the condenser, leading to a mineral-oil bubbler. Magnesium turnings (3.5 g, 0.144 mole) and 100 ml of sodium-dried diethyl ether...
