Stearic acid (/ ˈ s t ɪər ɪ k / STEER-ik, / s t i ˈ ær ɪ k / stee-ARR-ik) is a saturated fatty acid with an 18-carbon chain. [9] The IUPAC name is octadecanoic acid. [9] It is a soft waxy solid with the formula CH 3 (CH 2) 16 CO 2 H. [9]
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).

The effect of the tert-butyl group on the progress of a chemical reaction is called the Thorpe–Ingold effect illustrated in the Diels-Alder reaction below. Compared to a hydrogen substituent, the tert-butyl substituent accelerates the reaction rate by a factor of 240. [2] tert-Butyl effect. The tert-butyl effect is an example of steric hindrance.
Butyl oleate is a fatty acid ester and an organic chemical found in liquid form. It has the formula C 22 H 42 O 2 and the CAS Registry Number 142-77-8. [ 2 ] It is REACH registered and produced or imported into the European Union with the EC number of 205-559-6.
Similar monomers used are 1,6-hexanediol diacrylate and trimethylol propane triacrylate. It is a derivative of pentaerythritol [2] One of the key uses of the material is in polymeric synthesis where it can form micelles and block copolymers.

Pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate) is a chemical compound composed of four sterically hindered phenols linked through a pentaerythritol core. It is used as primary antioxidant for stabilizing polymers, particularly polyethylene and polypropylene.
Vinyl tributyltin is an organotin compound with the formula Bu 3 SnCH=CH 2 (Bu = butyl). It is a white, air-stable solid. It is used as a source of vinyl anion equivalent in Stille coupling reactions. [1] [2] As a source of vinyltin reagents, early work used vinyl trimethyltin, [3] but trimethyltin compounds are avoided nowadays owing to their ...
