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.
Cook the chicken until internal temperature reaches 170 degrees F. Large chicken breast 8-10 oz. 15 minutes on high coal heat (no black coals, ashed red coals), flip, 15 minutes on the other side. Chicken breast should be cooked until the internal temperature is 165 F no matter what way the chicken is cooked.
