Leonard and Musliner (50) found that the reaction of 2-cyclohexenone with pyrrolidine in the presence of p-toluenesulfonic acid led to the dimeric enamine (102). 

Solutioii of Citrate of Potassa. Take of citric acid, h ounce, troy bicarbonate of potassa, 330 mins water, f pint. Dissolve the acid and bicarbonate In the water, and stnun the solution through muslin. (U. S, PA)... 

Solution of Citrate of Iron. Dilute 1 pint of solution of tersulphate of iron with 2 pints distilled water precipitate with water of ammonia in slight excess, constantly stirring. Transfer the precipitate to a muslin strainer, and wash it with water until the washings are nearly tasteless. Drain it, and put half of it in a porcelain capsule on a water-bath heated to 150° Fabr., add 5 troy ounces citric acid in coarse powder, and stir until the precipitate is nearly dissolved then add sufficient of the reserved precipitate to fully saturate the acid. Lastly, filter tho liquid, evaporate it at a temperature not over lo0° Fahr, until it measures a pint. (U. S, Dis,)... 

Procedure. The method of acid extraction and demethylation of pectin from apple pomace at 60 C. was essentially that previously described (17), up to the point of clarification of the pectin extract. Prior to clarification, the temperature of the extract was raised to about 50 C. in order to aid dispersion of the pectinates. Following the clarification and removal of starch, the pectin was precipitated as calcium pectinate by adding 20% calcium chloride solution to the extract at room temperature. The quantity of calcium chloride was such that any excess of the salt did not give a further precipitate after the precipitated material had stood from 1 hour to overnight as a practical handling procedure. After the calcium pectinate had been filtered off through muslin by hand, the relative completeness of precipitation was estimated by determining the relative viscosity (Ostwald at 26 C.) of the liquid pressed out. A relative viscosity of 1.2 or less indicated practically complete precipitation. 

In another efficient approach to morphine (see Scheme 2.8), the 3,4-dihydro-benzylisoquinoline 36 is reduced with lithium in liquid ammonia, followed by A-formylation to give the amide 37. Acid-catalyzed cyclization of 37 gives the tetracyclic ketoamide 38. The 2-hydroxyl substituent is removed by the Musliner-Gates procedure, and the resulting material reduced to dihydrothebainone. The conversion of (— )-dihydrothebainone into ( —)-morphine has already been recorded.

Official Preparation of Antimony Trioxide (antimonii oxidum) — Sulplude of antimony in very fine powder, 4 oz. troy hydrochloric acid, 18 oz, troy nitric acid, 1 oz. troy liquor ammonise, IJ fl. oz. distilled water. The sulphide is put into a flask containing hydrochloric acid, and is then digested by means of a sand-bath until effervescence ceases. Thai add nitric acid gradually. When the nitrous acid vapours have ceased to be given off, the solution is allowed to cool. Add half a pint of water and filter. Pour the filtered liquid gradually into 12 pints of water, constantly stir it, and allow the precipitate to subside Decant the liquid and wash the precipitate twice- on each occasion with 8 pints of water. Then transfer it to a muslin filter to drain, and wash it until the acid reaction ceases. Introduce it into a vessel and subject it to the action of liquor ammonias for two hours. Then transfer it to a muslin filter and wash it until the filtrate gives no precipitate when silver nitrate is added. Dry it finally in a gentle heat.
