MEKP is a colorless oily liquid. It is widely used in vulcanization (crosslinking) of polymers. [3] It is derived from the reaction of methyl ethyl ketone and hydrogen peroxide under acidic conditions. Several products result from this reaction including a cyclic dimer. [4] The linear dimer, the topic of this article, is the most prevalent.
Diethyl toluene diamine (DETDA) is a liquid aromatic organic molecule [2] with formula C 11 H 18 N 2. It is chemically an aromatic diamine and has the CAS Registry number of 68479-98-1. It has more than one isomer and the mixture of the two main isomers is given a different CAS number of 75389-89-8. [3]
Usually Ziegler catalysts refer to titanium-based systems for conversions of ethylene and Ziegler–Natta catalysts refer to systems for conversions of propylene. Also, in the 1960s, BASF developed a gas-phase, mechanically-stirred polymerization process for making polypropylene. In that process, the particle bed in the reactor was either not ...
Diethylenetriamine (abbreviated Dien or DETA) and also known as 2,2’-Iminodi(ethylamine) [2]) is an organic compound with the formula HN(CH 2 CH 2 NH 2) 2.This colourless hygroscopic liquid is soluble in water and polar organic solvents, but not simple hydrocarbons.
Aliquat 336 is used as a phase transfer catalyst, [2] including in the catalytic oxidation of cyclohexene to 1,6-hexanedioic acid. [3] This reaction is an example of green chemistry, as it is more environmentally friendly than the traditional method of oxidizing cyclohexanol or cyclohexanone with nitric acid or potassium permanganate, which produce hazardous wastes.
This orange-red liquid is a valuable reagent but also quite dangerous and explodes upon heating. Therefore, commercial shipment of pure diethyl azodicarboxylate is prohibited in the United States and is carried out either in solution or on polystyrene particles.
Addition of further Bisphenol A and a catalyst and heat can produce Bisphenol A glycidyl ether epoxy resins of higher molecular weight that are solid. [ 8 ] Structure of bisphenol-A diglycidyl ether epoxy resin: n denotes the number of polymerized subunits and is typically in the range from 0 to 25
When the system is liquid, the storage modulus is very low: the system behaves like a liquid. Then the reaction continues and the system starts to react more like a solid: the storage modulus increases. The degree of curing, , can be defined as follow: [8]
