What is a chemical property? Perhaps it has something to do with the chemical makeup of matter? Or perhaps it is related to thechemical changesmatter goes through? This lesson will examine the chemical property definition and give some examples of chemical properties. ...
According to LeeCronin(Figure 7), chemists make very complicated molecules by “chopping up” small molecules and “reverse engineering” them. He wonders if we could “make a really cool universal chemistry set” by what he calls “app-ing” chemistry. Could we “app” chemistry? In a 2012...
Major transportation pipelines usually impose restrictions on the makeup of the natural gas that is allowed into the pipeline and cleaning before transportation is required. While the ethane, propane, butane, and pentanes must be removed from natural gas, this does not mean that they are all ...
The petrochemical SA production routes include catalytic hydrogenation or electrolytic reduction of maleic acid or maleic anhydride, which are obtained by oxidation of benzene or butane, resulting in succinic anhydride, which on hydrolysis forms SA [4,11]. However, these routes use non-renewable feeds...
These kinds of fundamental studies have opened new avenues to implement metabolic engineering strategies using CRISPR–Cas system wherein little is known about the genetic makeup of organism and it displays weak DNA repair ability besides lack of expression plasmids and promoters for expressing guided ...

The synthesis of 1-substituted homotropanones, under stereocontrolled conditions, is detailed by employing chiral N-tert-butanesulfinyl imines as intermediate reaction species. Key procedures of this methodology are the reaction of organolithium and Grignard reagents with hydroxy Weinreb amides, followed...
If the amount of blowdown water is significant, then in addition to flash steam recovery, sensible heat recovery from blowdown water will also be economical. Such a system consists of a flash tank and a heat exchanger to preheat deaerator makeup water as shown inFigure 1. It saves steam ...
Nonhomogeneous indicates that the solid mass may have an uneven or nonuniform chemical or physical makeup. For example, a nonhomogeneous mass may comprise a solid detergent cleaner containing a nonionic surfactant and encapsulated chlorine granules. The incompatibility of the nonionic surfactant and ...
the second polymerization and recycle are operated to reduce the ethylene monomers to a level below what is required for making the first polymer, with additional makeup propylene monomer being added for the first polymerization and additional makeup ethylene monomer being added for the second polymer...
