Potassium Methylate. Potassium methoxide [865-33-8] KOCH, mol wt 70.13, is a fine, free-flowing, yellowish-white, caustic, hygroscopic powder purity 96.5—99% powder density after loose shaking, 0.75 g/mL apparent density (packing weight), 1.00 g/mL medium grain size, 0.05 —0.8 mm easily soluble in alcohols (33% in methanol at 20°C), insoluble in hydrocarbons. 

Note Since the azide had been packed usually a day or more before the moisture detn was completed, it was necessary to calculate in advance the wt of wet azide to pack in order that each bag should contain 25 lbs of dry LA. For this purpose it was assumed that the moisurre content of the lot (four drums) being packed would be approx the same as the ave of the ten preceding analyzed lots. From this ave value, the wt of wet material equiv to 25 lbs of dry LA was calqd. This result, plus a tare of containers constitutes the pack weight (Ref 9, p 54)...
