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 ...
the parent compound, used as a disinfectant and for chemical synthesis: Bisphenol A: and other bisphenols produced from ketones and phenol / cresol BHT (butylated hydroxytoluene) - a fat-soluble antioxidant and food additive: 4-Nonylphenol: a breakdown product of detergents and nonoxynol-9: Orthophenyl phenol: a fungicide used for waxing citrus ...
In the 19th century, and possibly earlier, Persian merchants used a slightly modified linear Taylor approximation to the monthly payment formula that could be computed easily in their heads. [6] In modern times, Albert Einstein's supposed quote regarding compound interest rings true. "He who understands it earns it; he who doesn't pays it." [7]
Here’s what the letters represent: A is the amount of money in your account. P is your principal balance you invested. R is the annual interest rate expressed as a decimal. N is the number of ...
2,4-Di-tert-butylphenol (2,4-DTBP) is a white solid with a phenolic odour. It is primarily used as a raw material for the production of several commercially important antioxidants and phenolic benzotriazole-type UV absorbers. It also finds use as a starting material in the synthesis of agrochemicals, fragrances and catalysts (i.e. Jacobsen's ...
2,4,6-Tri-tert-butylphenol is a white solid which dissolves in many organic solvents, but not in aqueous or alcoholic alkaline solutions. The green-blue coloring with iron(III)chloride, which is characteristic for phenols, does not occur in 2,4,6-TTBP. The compound is oxidizable in air but practically non-biodegradable. [7]
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] Illustrative of its usefulness, it prevents ...
The classical formula for the present value of a series of n fixed monthly payments amount x invested at a monthly interest rate i% is: = ((+))The formula may be re-arranged to determine the monthly payment x on a loan of amount P 0 taken out for a period of n months at a monthly interest rate of i%:
