Product 1

HCID 22757682N-Butyl-3,5-di-tert-butyl-4-hydroxybenzamide

Procedure

In the manner of Example 1, n-butylamine was reacted with 3,5-di-t-butyl-4-hydroxybenzoyl chloride to produce N-n-butyl-3,5-di-t-butyl-4-hydroxybenzamide; melting point 181°-183°C. When tested by the procedure in Example 2, the sample containing this compound lasted 950 hours, about 3.2 times as long as the control.
