What has the author James Wayne Gordon written?
James Wayne Gordon has written: 'Mechanism of the olefin iodochlorination reaction'
What is the effect of olefin concentration on naphtha hydrotreating process?
Hydrotreating reaction is an exothermic reaction. The total reaction provides excess reaction heat; more is produced by the exothermic hydrogenation reactions than are required to support the endothermic cracking reactions.High Olefin conc. leads to high temp. rise due to hydrogenation reaction.This excess heat increases the reactor temperature and accelerates the reaction rate. Temperature rise can be controlled by injecting cold hydrogen or cold recycled quench into the reactors to absorb excess reaction heat.
Is olefin a natural fiber?
no, "Olefin is a manufactured fiber in which the fiber-forming substance is any long-chain synthetic polymer composed of ethylene Propylene or other olefin units". (Kaldolph, 2010)
Are olefin and microfiber the same thing?
Both olefin and microfiber are synthetic fibers, though they are made from different processes. Olefin is made using ethylene or propylene. Microfiber is made by combining thin strands of polyester and nylon.
Is there an Allergic reaction to olefin fiber?
Yes, especially if you are chemically sensitive. I had to throw my rugs out because it made me fill up with phlem and cough. Once removed my symptoms disappeared.
What is a synthetic fabric beginning with a?
Olefin
What are the disadvantages to olefin?
IT CRUSHES & MATTS...WILL LOOK LIKE CRAP IN 2 YEARS - GET HEAT SET 100% NYLON what are the disadvantages to olefin
What is olefin saturation?
Olefin Saturation is a chemical process, often used in the petrochemical industry to refine olefins (also known as alkenes) and to turn them into paraffins (also known as alkanes). The process is done by adding hydrogen gas to the heated liquid olefin. This breaks the carbon to carbon double bond of the olefin by forming a new molecule with extra hydrogen.
What country does olefin fiber come from?
italy
What is the lightest weight manufactured fiber?
Olefin
Is olefin a thermoplastic or thermoset polymer?
Thermoplastic olefin is a plastic that helps absorb the energy from a crash or bump. And when you crash into something that is also made of thermoplastic olefin, it will bump back to you which will cause different forces. Like in Newtons first and third law of motion
Why are alkane called olefins?
Alkenes are also called OLEFINS because they form oily liquids on reaction with chlorine gas.
