उदाहरण वाक्य

1. :( Oh-and incidentally, you don't need to distil your own glacial acetic acid-you can buy a bottle for $ 17 on Amazon . com ! ) talk ) 12 : 29, 19 June 2013 ( UTC)
2. Would it also be safe to use reagents like glacial acetic acid ( to avoid too much starting water ) or oxalic acid as long as you neutralised or diluted the mixture to a safe pH afterwards?
3. In a typical procedure, the fatty acid is treated with an excess of the Hanua
   or Wijs solution, which are, respectively, solutions of iodine monobromide ( IBr ) and iodine monochloride ( ICl ) in glacial acetic acid.
4. The original Knorr synthesis employed two equivalents of ethyl acetoacetate, one of which was converted to ethyl 2-oximinoacetoacetate by dissolving it in glacial acetic acid, and slowly adding one equivalent of saturated aqueous sodium nitrite, under external cooling.
5. Glacial acetic acid can be used to obtain a mixture high in 6-monoacetylmorphine, niacin ( vitamin B 3 ) in some form would be precursor to 6-nicotinylmorphine, salicylic acid may yield the salicyoyl analogue of 6-MAM, and so on.
6. He worked with Lavoisier on a new chemical notation system, and was secretary to the scientific periodical " Annales de chimie ", founded in 1789 . He proved that glacial acetic acid and vinegar acetic acid were the same substance.
7. Yields were significantly improved, by the use of preformed diethyl aminomalonate ( prepared by the hydrogenolysis of diethyl oximinomalonate in ethanol, over Pd / C ), and adding a mixture of diethyl aminomalonate and the beta-diketone to actively boiling glacial acetic acid.
8. Each single-use vial of reslizumab is formulated as 10 mg / mL reslizumab in an aqueous solution containing 2.45 mg / mL sodium acetate trihydrate, 0.12 mg / mL glacial acetic acid, and 70 mg / mL sucrose, with a pH of 5.5.
9. A small sample is dissolved in water or saline, glacial acetic acid is added to hydrolyze the insoluble salts of fatty acids, a few drops of alcoholic solution of Sudan III are added, the sample is spread on a microscopic slide, and heated twice to boil.
10. The reaction conditions for the Kr�hnke synthesis are generally facile and the reactions often proceed in high yields with reaction temperatures generally not exceeding 140 �C . The Kr�hnke synthesis is generally performed in either glacial acetic acid or methanol, but it can also be done under aqueous conditions, and more recently under solvent-free conditions.
