Butyric acid, along with acetic acid, can be reacted with cellulose to produce the organic ester cellulose acetate butyrate (CAB), which is used in a wide variety of tools, parts, and coatings and is more resistant to degradation than cellulose acetate.
One and a half hours is much too long to cook the chicken at 350 degrees F. The time your chicken will bake in the oven does depend on the internal temperature and the size of your chicken or chicken pieces. Generally I bake chicken at 350 degrees F. for 30 to 40 minutes.
To safely destroy dangerous bacteria the internal temperature of cooked chicken should reach no less than 165 degrees Fahrenheit. This is the minimum temperature for safe cooking, however, for maximum safety a higher chicken cooking temperature may be preferable, particularly for breast meat and whole chickens. For whole chickens 180 degrees is a safe temperature, and 170 degrees Fahrenheit is safest for chicken breasts.
