The meaning of ETHYLENE is a colorless flammable gaseous unsaturated hydrocarbon C2H4 that is found in coal gas, can be produced by pyrolysis of petroleum hydrocarbons, and occurs in plants functioning especially as a natural growth regulator that promot

Ethylene biosynthesis is derived from the amino acid methionine provided by the Yang cycle [12], in which the precursor S-adenosylmethionine (AdoMet or SAM) is synthesized from ATP and methionine by S-adenosylmethionine synthetase (SAMS; EC 2.5.1.6) [13]. AdoMet is then converted into 1-aminoc...
The synthesis and properties of a macromolecular nanocapsule derived from hyperbranched polyethylenimine (HPEI) with well-defined hybrid shell of poly(ethylene oxide) monomethyl ether (mPEO) and polystyrene (PS) are described. HPEI is treated in sequence with 4-glycidol-2,2,6,6-tetrametyl-piperi...
Atomic and bond-topological properties were derived using the atoms-in-molecules (AIM) formalism. The high strain in the three-membered ring molecule is mainly expressed by the high ellipticities of the three bonds in this ring, while the bond paths are only slightly bent for the C-C bond,...
Methyl methacrylateis embryotoxic and fetotoxic to rats (as is toluene). Though there is no evidence of such a danger to humans from methyl methacrylate, this should be borne in mind as a hazard, but probably no more than a theoretical one, in the case of femaledental technicians. ...
We report here a synthesis of para-xylene, one of the highest volume chemicals derived from petroleum, using only ethylene as a feedstock. Ethylene is an attractive alternative feedstock, as it can be derived from renewable biomass resources or harnessed from large domestic shale gas deposits. ...
The compound is generally produced through the hydration of ethylene oxide, which is derived from petroleum or natural gas. In this process, ethylene oxide is reacted with water under controlled conditions, often with the help of a catalyst to facilitate the reaction. Ethylene glycol is toxic,...
For the simple alkyl groups, resistance is correlated to the length the alkyl chain (35). Thus, the greater the bulk emanating from the 2′-position, the greater the t1/2 in nuclease assays. The relative stabilities of several 2′-O-alkyl-modified RNA have the following order c...
Ethylene is an important petrochemical product used mostly as a raw material in the manufactures of polymers. In a typical ethylene plant, the separation of ethylene and ethane is a key stage in the whole production chain. Several methods are known for separation of ethylene from gaseous mixtures...
