As each phenol group contains only a single t-butyl group they are considered to have low steric hindrance and thus high activity. Arranging three of these around an isocyanurate core gives a compound with a sufficiently high boiling point that it is not volatilised out of the plastic during plastic extrusion and moulding (up to 320 °C in the case of PA).
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
It is a soft waxy solid with the formula CH 3 (CH 2) 16 CO 2 H. [9] The triglyceride derived from three molecules of stearic acid is called stearin . [ 9 ] Stearic acid is a prevalent fatty-acid in nature, found in many animal and vegetable fats, but is usually higher in animal fat than vegetable fat.
Butan-2-yl (sec-butyl) group is chiral. The carbon atom at position 2 is a stereocenter. It has four different groups attached: −H, −CH 3, −CH 2 −CH 3, and −R (the R group is not equal to those three groups). The names of the two chiral groups are: (2S)-butan-2-yl and (2R)-butan-2-yl.

Sodium tert-butoxide (or sodium t-butoxide) is a chemical compound with the formula (CH 3) 3 CONa (abbr. NaOtBu). [2] It is a strong, non-nucleophilic base.It is flammable and moisture sensitive.
They are coplanar in the hydrated salts NaHC 4 O 4 ·2H 2 O and CsHC 4 O 4 ·2H 2 O, nearly coplanar in the guanidinium salt [C(NH 2) 3] + [HC 4 O 4] −, but off by 60° or more in other salts such as anhydrous KHC 4 O 4.
