Not illustrated. 1898 edition. Excerpt: ...is indeed anhydrous normal ammonium imidosulphonate. To Woronin is due the accurate distinction between the two salts. The mother-liquor of the crystals of the two-thirds normal ammonium imidosulphonate (' parasulphatammon') gave Rose on evaporation his so-called 'deliquescent salt.' This Berglund considered, it appears from his later paper on Amidosul phonic acid, to have been a mixture of amidosulphonate and the two-thirds normal imidosulphonate with ammonium acid sulphate. Sodium imidosulphonates.--That, contrary to Fremy's experience, sodium nitrite can be sulphonated as easily as potassium nitrite was ascertained by Raschig and by u.s about the same time, and later we ourselves prepared the normal and two-thirds normal sodium salts, as well as some compound salts. Berglund, however, had prepared the normal sodium salt and also the mercury sodium salt, but not by sulphonating sodium nitrite. He either boiled ammonium imidosulphonate with sodium hydroxide till all ammonia had been expelled, or, more satisfactorily, he precipitated by potassium chloride the two-thirds normal potassium salt from the ammonium salt; dissolved it in a boiling solution of sodium hydroxide and chloride; and then by cooling crystallised out the normal sodium salt. His description of the normal sodium salt, so far as it goes, agrees with ours. The crystalline salt which he sometimes got in place of the ordinary normal sodium salt, and which he believed to be that salt in the anhydrous state, we take to have been a double salt of normal sodium imidosulphonate and potassium chloride. He did not obtain the two-thirds normal sodium imidosulphonate, nor its compounds with ammonium nitrate and with potassium nitrate, nor sodium ammonium imidosulphonate. Barium...show more
