The vapor space above liquid ethylene oxide(EO)in storage tanks must be purged of oxygen and then padded with81psig nitrogen to prevent explosion. The nitrogen in a particular facility is supplied from a200psig source. It is regulated to...
Prepared from ethylene oxide; by addition of carbon dioxide; with ammonium; or alkali metal salts as catalysts. 3.4 Purification Methods Dry 1,3-dioxolan-2-one over P2O5, then fractionally distil it at low or atmospheric pressure. Recrystallise it from dry Et2O (plates, m 36.5o, 38.5-40o ...
nitrous oxide or laughing gas (N2O). The molecules (H2, O2, Ar, N2 and CO) separated by the first channel co-elute as one peak on this channel. A Rt-U-BOND PLOT (15 m × 0.53 mm i.d., 20 μm film thickness; Restek) is used as a pre-column to backflush H2O and a Rt-Q...
A crystalline block copolymer of poly(ethylene-block-ethylene oxide) (PE-b-PEO) was successfully grafted onto a carbon black surface by direct condensation of its terminal hydroxyl groups with carboxyl groups on the surface using N,N'-dicyclohexylcarbodiimide as a condensing agent. The electric res...
Application: GC9802-K Face Mask Ethylene Oxide (EO) Residuals Testing Gas Chromatography has a reasonable structure, stable and reliable performance, simple operation and convenient maintenance and it can be widely used in petroleum, chemical industry, pesticides, medicine and health, commodity inspectio...
A crystalline block copolymer of poly(ethylene- block -ethylene oxide) (PE- b -PEO) was successfully grafted onto a carbon black surface by direct condensation of its terminal hydroxyl groups with carboxyl groups on the surface using N , N ′-dicyclohexylcarbodiimide as a condensing agent. The...
Pentane (10 mL) was added to the crude residue, which was subsequently removed under reduced pressure, this was then repeated. Pentane (25 mL) was added again, and solid triphenylphosphine oxide precipitated. The solid was removed by filtration then washed with pentane (25 mL). The pentane ...
It is advantageous here to throttle the vapor stream from 5-2 to 5-1 to the lower pressure with the aid of a closed-loop control valve or closed-loop control flap, or to undertake the throttling using a turbine that drives a motor that generates flow. The vapors can be passed into an...
