2,6 Di-tert-butyl-para cresol Butylated Hydroxy Toluene (2,6 DBPC)
Introduction:
A white Crystalline solid having a faint characteristics odor. It is insoluble in water and in propylene glycol, but is freely soluble in alcohol.
 
Chemical Name : 2,6 Di-tert-butyl-para cresol ( 2,6 DBPC ) Butylated Hydroxy Toluene
CAS No. : 128-37-0
Structural Formula :
Formula wt. : 220.35
 
Requirements:
Identification to 10 ml f a 1 in 100,000 solution of the sample in methanol add 10 ml of sodium nitrite solution (3 in 1000), and 5 ml of dianisidine solution(200 mg of 3,3'-dimethoxybenzidine dihydrochloride dissolved in a mixture of 40 ml methanol and 60 ml of 1N hydrochloric acid). An orange-red color develops within 3 min. Add 5 ml of chloroform and shake. The chloroform layers exhibits a purple or magenta color that fades when exposed to light.
 
Tests:
Solidification Point : not less than 69.2°C
Purity : not less than 99.0%
Residue on Ignition : Transfer a 50 g sample into a tared crucible, ignite until thoroughly charred, and cool.. Moisten the ash with 1 ml of sulphuric acid and complete the ignition by heating for 15-min periods at 800 °C ± 25 °C
 
Storage:
Store in well-closed container.
