C22H38O4Zn -- 431.92
10-Undecenoic acid, zinc(2+) salt.
Zinc 10-undecenoate CAS 557-08-4Zinc Undecylenate contains not less than 98.0 percent and not more than 102.0 percent of C22H38O4Zn, calculated on the dried basis.
Identification:
A: Acidify about 5 g with 25 mL of 2 N sulfuric acid, add 20 mL of water, and extract in a separator with two 25-mL portions of ether. Evaporate the ether solution until the odor of ether no longer is perceptible. Add potassium permanganate drop-wise to a 1-mL portion of this residue: the permanganate color is discharged.
B: A 3-mL portion of the residue of undecylenic acid obtained in Identification test A responds to Identification test B under Undecylenic Acid.
C: Dissolve about 100 mg in a mixture of 10 mL of water and 1 mL of ammonium hydroxide, and add a few drops of sodium sulfide: a white, flocculent precipitate of zinc sulfide is formed.Loss on drying: Dry it at 105 for 2 hours: it loses not more than 1.25% of its weight.
Alkalies and alkaline earths: Boil 1.50 g with a mixture of 50 mL of water and 10 mL of hydrochloric acid, filter while hot, and wash the separated acid with about 50 mL of hot water. Render the combined filtrate and washings alkaline with 6 N ammonium hydroxide, add ammonium sulfide to precipitate the zinc completely, dilute with water to 200 mL, mix, and filter. To 100 mL of the clear filtrate add 0.5 mL of sulfuric acid, evaporate to dryness, and ignite over a low flame to constant weight: the weight of the residue does not exceed 7.5 mg (1.0%).We also supply Zinc Undecylenate or Zinc Undecenoate BP Ph Eur grade.
