It has also found use as a plasticizer. Bisphenol A is difunctional and used to produce epoxy resin and polycarbonate. 4-tert-Butylphenol is monofunctional and so in polymer science terms, bisphenol A is a polymer chain extender but 4-tert-butylphenol is a chain stopper or sometimes called endcapper. It is thus use to control molecular weight ...
Synthese von 2,4,6-Tri-tert-butylphenol mit Isobuten. A synthesis of 2,4,6-tri-tert-butylphenol has been described that is also suitable as a teaching experiment. Methyl tert-butyl ether is used as the alkylating agent and sulfuric acid as catalyst. 2,4,6-TTBP is being obtained in 69% yield. [6] Synthese von 2,4,6-TTBP mit Methyl-tert ...
Chemistry stencils that used to be used for drawing equipment in lab notebooks. A laboratory notebook ( colloq. lab notebook or lab book ) is a primary record of research . Researchers use a lab notebook to document their hypotheses , experiments and initial analysis or interpretation of these experiments.
C 4 H 9 Cl Molar mass: 92.57 g/mol ... In the laboratory, ... tert-Butyl chloride is used to prepare the antioxidant tert-butylphenol and the fragrance neohexyl ...
Tris(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate is a chemical compound used as a polymer stabilizer in plastics. Like other hindered phenols it acts as a primary antioxidant . More than 1000 tonnes per year are used in the EU.
Bis(2,4-di-tert-butylphenyl) pentaerythritol diphosphite is an organophosphite used as a polymer stabilizer in plastics. Like other phosphite antioxidants it primarily acts to remove hydroperoxides and is typically used in combination with hindered phenolic antioxidants such as pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate) .
2,6-Di-tert-butylphenol is an organic compound with the structural formula 2,6-((CH 3) 3 C) 2 C 6 H 3 OH. This colorless solid alkylated phenol and its derivatives are used industrially as UV stabilizers and antioxidants for hydrocarbon -based products ranging from petrochemicals to plastics. [ 1 ]
Para tertiary butylphenol formaldehyde resin, also known as p-tert-butylphenol-formaldehyde resin (PTBP-FR), is a thermoplastic phenol-formaldehyde resin found in commercial adhesives, particularly glues used to bond leather and rubber. It has broad usage in a large variety of industries and can be found in many household textile products and ...
