Butylated Hydroxytoluene
CAS Number: 128-37-0
Molecular Formula: C15H24O
Molecular Weight: 220.35
Butylated Hydroxytoluene
Butylated Hydroxytoluene USP NF Grade Specifications
C15H24O --- 220.35
Phenol, 2,6-bis(1,1-dimethylethyl)-4-methyl-.
2,6-Di-tert-butyl-p-cresol CAS 128-37-0
Butylated Hydroxytoluene contains not less than 99.0 percent of C15H24O.
Identification: To 10 mL of a solution in methanol (1 in 100,000) add 10 mL of water, 2 mL of sodium nitrite solution (3 in 1000), and 5 mL of dianisidine dihydrochloride solution (1 in 500), prepared by dissolving 200 mg of dianisidine dihydrochloride in a mixture of 40 mL of methanol and 60 mL of 1 N hydrochloric acid: an orange-red color develops within 3 minutes. Add 5 mL of chloroform, and shake: the chloroform layer exhibits a purple or magenta color, which fades when exposed to light.
Congealing temperature: not lower than 69.2, corresponding to not less than 99.0% of C15H24O.
Residue on ignition: Transfer about 50 g, accurately weighed, to a tared crucible, ignite until thoroughly charred, and cool. Moisten the ash with 1 mL of sulfuric acid, and complete the ignition by heating at 800C ± 25C for 15-minute periods to constant weight: the limit is 0.002%.
Heavy metals: 0.001%.
BHT Butylated Hydroxytoluene, 2,6-Di-tert-butyl-p-cresol FCC Food Grade
C15H24O, Formula weight 220.35
INS: 321 CAS 128-37-0
DESCRIPTION
BHT occurs as a white, crystalline solid. It is freely soluble in alcohol, and insoluble in water and in propylene glycol.
Function: Antioxidant.
REQUIREMENTS
Identification: Dissolve 200 mg of 3,3′-dimethoxybenzidine dihydrochloride in a mixture of 40 mL of methanol and 60 mL of 1 N hydrochloric acid. Add 5 mL of the resulting dianisidine solution to 10 mL of water and 2 mL of a 3:100 solution of sodium nitrite. Add this solution to 10 mL of a 1:100,000 solution of sample methanol. An orange-red color appears within 3 min. Add 5 mL of chloroform, and shake. The chloroform layer exhibits a purple or magenta color that fades when exposed to light.
Assay: Not less than 99.0% of C15H24O.
Residue on Ignition: Not more than 0.002%.
We also supply Butylated Hydroxytoluene of BP Ph Eur Grade.
BHT gives greater synergistic effect with TBHQ, BHA and propyl gallate than that which might be expected from contribution of each individual antioxidant.
