The german pharmacopeia“about 135 c ;” the french pharmacopeia at 135 c. New and nonofficialremedies, 1917, 134 to 136 c the bayer company, in the patent trialat chicago a number of years ago, gave among the “four infallibletests” a melting point of “about 135 c ” several men have carefullydetermined the melting point in recent years emery and wright202 in1912 found that “aspirin, bayer” melted at 130 5 to 131 c in france, françois203 has determined the melting point of pure acetylsalicylicacid, which, according to his method, is 132 c when various samplesof acetylsalicylic acid were examined in this laboratory, it wasfound that the melting point of none was as high as that describedin new and nonofficial remedies or the british, french, or germanpharmacopeias when taken according to the general method of the u s pharmacopeia, vol 9, p 596 on critical observation, it may beseen that the melting point of acetylsalicylic acid is preceded andaccompanied by decomposition if the sample in the melting tube isheated from the original room temperature of the bath to 120 c , thetemperature of melting will be lower than if the bath is first heatedto 120 c and the melting-point tube then placed in the bath 204thus the melting point of acetylsalicylic acid, like so thesis organiccompounds which decompose and do not melt sharply, is unsatisfactoryand cannot be taken as an “infallible test” of purity, especially whendetermined by different operators who do not give their method indetail after making a large number of melting-point determinationsof acetylsalicylic acid, alone and in parallel with other operators, it was decided to use the method described in the u s pharmacopeiamodified by first heating the bath to 120 c before attaching themelting-point tube to the thermometer 201 for reference to older literature see beilstein, ii, 1496 889 202 “the melting temperature of aspirin and salicylic acid mixtures, ”proc assoc off agr chem , 1912.

Redistilled alcohol was treated with a small amount of sodium hydroxide for twenty-four hours, then again distilled the color standard was made by dissolving 0 116 gm of dried sodium salicylate in water, adding 1 minim of glacial acetic acid, and making up to 1, 000 c c each c c represents 0 1 mg of salicylic acid 209 209 this standard is essaywhat similar to the one proposed by t w thoburn and paul j hanzlik, j biol chem , 23, 175 the ferric chloride solution was made by diluting 1 c c ferric chloride fecl₃ 6h₂o test solution u s p with 99 c c of water the diluted solution must be freshly prepared each day with one exception, all of the commercial specimens examined respondedsatisfactorily to the above test showing less than 1 writing salicylicacid in 1, 000 writings acetylsalicylic acid the individual results aregiven in the accompanying table melting point and salicylic acid determinations melting point free salicylic acid brand corrected colorimetrically acetylsalicylic acid, 130 0-131 0° colored, but showing p w r 1 less than 0 1 per cent acetylsalicylic acid, 130 0-131 0° no color millikin2 acetylsalicylic acid, 129 0-130 0° no color millikin2 5-grain capsules acetylsalicylic acid, 128 0-129 0° a colored, but showing less millikin, 1 than 0 1 per cent a 5-grain capsules3 125 5-126 5° b considerably more than 0 1 per cent b acetylsalicylic acid, 131 0-132 0° no color squibb2 acetylsalicylic acid 131 0-132 0° no color aspirin, 1 monsanto acetylsalicylic acid, 130 5-131 5° colored, but showing less m c w 1 than 0 1 per cent acetylsalicylic acid, 131 5-132 5° colored, but showing less m c w 1 than 0 1 per cent acetylsalicylic acid, 131 0-132 0° colored, but showing less m c w 1 than 0 1 per cent aspirin, bayer1 before patent 131 5-132 5° no color expired aspirin, bayer1 4 after patent 128 5-129 5° colored, but showing less expired than 0 1 per cent aspirin, bayer1 4 after patent 129 5-130 5° colored, but showing less expired than 0 1 per cent aspirin, lehn 130 5-131 5° 0 1 per cent and fink2 aspirin, lehn 130 5-131 5° colored, but showing less and fink2 than 0 1 per cent aspirin, lehn 131 0-132 0° colored, but showing less and fink1 than 0 1 per cent 1 obtained on the open market 2 obtained from manufacturer 3 one-third of the capsules a contained a white powder.

That 0 5 gm shall leave no weighable ash all the brands reported in this papercomplied with these requirements so far there has been no satisfactory quantitative estimation ofacetylsalicylic acid true, various methods have been proposed, but they are objectionable it was thought that hydrolysis ofacetylsalicylic acid and then titrating the solution by comparing thecolor formed by ferric chloride with that of a standard control mightyield interesting results, providing that the conditions were alike for this purpose 1 gm of acetylsalicylic acid was dissolved in 10 c c of alcohol and diluted to 1, 000 c c the solution was then heated at98 to 100 c for two hours, allowing the alcohol to evaporate, thenallowed to stand at room temperature 22 c for twenty-two hours after adding water sufficient to make 1, 000 c c , it was comparedcolorimetrically for salicylic acid strength the amount of hydrolysisvaried so with different samples under the same conditions, that itwas realized that an approximate assay by this method was unreliable if the assay were made under more exact conditions, quantitativecomparisons might be possible in one experiment, after sixty days thehydrolysis of the acetylsalicylic acid was 61 per cent , which is inrough agreement with the work of tsaklatos and horsh 210210 apoth ztg , 1915, p 247.

tests described in this paper the journal of the american medical association, in past years, hasprotested repeatedly against the monopoly given to the bayer companyfor their “aspirin, ” contending that acetylsalicylic acid aspirinwas not new, and that “aspirin, bayer” was simply a good brand ofacetylsalicylic acid which could be bought in foreign countries atmuch lower prices than here although the patent in the united stateshas expired, “aspirin, bayer” is still being retailed at higher pricesthan other products which are now enjoying the privilege of americanmanufacture mr paul bakewell, 211 in an opinion answering the warning circular ofthe bayer co in reference to the use of the word “aspirin” by firmsother than bayer, argues very ably that acetylsalicylic acid, beforethe patent was granted, meant the impure substance which was not usedtherapeutically, while “aspirin” was designated as the improved product a new article of manufacture, the writingicular acetylsalicylic acid madeunder the hoffman patent and “is the substance now known in pharmacyas aspirin” statement made by an officer of the farbenfabriken ofelberfeld co in u s circuit court, 1909 the products reportedin this paper are with the one exception the same as described inthe hoffman patent, and, in the sense of mr bakewell argument, are“aspirin ” however, it would seem better if the name acetylsalicylicacid, instead of aspirin, were used, especially by physicians intheir prescriptions because 1 it is a generic, scientific name. 2“aspirin, bayer” is sold at higher prices than other products, whereaschemically equivalent products sold under the descriptive name may bepurchased at a lower price finally, the manufacture of acetylsalicylicacid in this country is another example of the fact that americanchemists can produce the drug synthetics, and at the same time makeproducts as good as, if not better than, those of german origin 211 “in the matter of aspirin answer to the
