Mechanism proposed for the ring-opening polymerization of caprolactone to polycaprolactone by TBD. [5] [6]As a strong base, TBD fully deprotonates most phenols, carboxylic acids, and some C-acids. [7]
Tax deduction at source (TDS) has come into existence with the motive of collecting tax from different sources of income. As per this concept, a person (Payer) who is responsible to make payment of specified nature to any other person (Payee) shall deduct tax at source before making payment to such person (Payee) and remit the same into the account of the Central Government.
Isophorone diamine (usually shortened to IPDA) is a chemical compound and specifically a diamine with the formula (CH 3) 3 C 6 H 7 (NH 2)(CH 2 NH 2). It is a colorless liquid. It is a precursor to polymers and coatings. [1]
Moisture analysis covers a variety of methods for measuring the moisture content in solids, liquids, or gases.For example, moisture (usually measured as a percentage) is a common specification in commercial food production. [1]
In normal potable water production without the requirement of high recoveries, reverse osmosis is generally believed to be more cost-effective when total dissolved solids (TDS) are 3,000 parts per million (ppm) or greater, while electrodialysis is more cost-effective for TDS feed concentrations less than 3,000 ppm or when high recoveries of the ...
Trichloroethylene (TCE) is a halocarbon with the formula C 2 HCl 3, commonly used as an industrial metal degreasing solvent.It is a clear, colourless, non-flammable, volatile liquid with a chloroform-like pleasant mild smell [3] and sweet taste. [9]
Water chemistry analysis is often the groundwork of studies of water quality, pollution, hydrology and geothermal waters. Analytical methods routinely used can detect and measure all the natural elements and their inorganic compounds and a very wide range of organic chemical species using methods such as gas chromatography and mass spectrometry.
