Potential Exposure
Ethylene oxide is a man-made chemical used in the production of glycols (ethylene glycol, polyglycols, glycol ethers, esters), nontonic surface-active
agent; ethanolamines, acrylonitrile, plastics. It is also used
as a fumigant for foodstuffs and textiles; an agricultural
fungicide; and for sterilization, especially for surgical
instruments. It is used in drug synthesis and as a pesticide
intermediate

chemically and/or polymerize violently with evolution of
heat; when in contact with highly active catalytic surfaces,
such as anhydrous chlorides of iron, tin and aluminum;
pure oxides of iron and aluminum; and alkali metal hydroxides. Even small amounts of strong acids; alkalis, or oxidizers can cause a reaction. Avoid contact with copper.

Check Digit Verification of cas no
The CAS Registry Mumber 99932-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,3 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99932-75:
(7*9)+(6*9)+(5*9)+(4*3)+(3*2)+(2*7)+(1*5)=199
199 % 10 = 9
So 99932-75-9 is a valid CAS Registry Number.

PRODUCTION PROCESS OF ALKYLENE OXIDES FROM ALKYLENE CARBONATES

Page/Page column 10-12, (2022/04/03)
Catalytic process for producing alkylene epoxide, selected between ethylene oxide or propylene oxide, from the corresponding alkylene carbonate, selected between ethylene carbonate or propylene carbonate, comprising the decomposition reaction of alkylene carbonate, in the presence of sodium bromide as catalyst, in which: the reaction temperature is between 207 and 245°C, and the catalyst is in amounts comprised between 5x10-4 and 8x10-3 moles per mole of alkylene carbonate. This process can be carried out continuously. A further object of the invention is the modular plant which allows carrying out such a process.
Epoxidation of Ethylene with Products of Thermal Gas-Phase Oxidation of n-Butane

Abstract: Epoxidation of ethylene with the reactive products formed during thermal gas-phase oxidation of n-butane has been carried out under flow conditions with the separation of the zones of generation of radicals and their interaction with ethylene. Butane is oxidized in the first section of a two-section reactor, and ethylene is fed to the second section. It has been found that increasing the residence time of a butane–oxygen mixture in the first section of the reactor from 7 to 13 s increases the ethylene oxide accumulation rate. A further increase in the contact time leads to a decrease in the rate. Similarly, increasing the C4H10/O2 ratio in the range of 0.05–0.25 leads to an increase in the rate of accumulation of ethylene oxide. A further increase in this ratio decreases the rate of epoxidation. It has also been found that the temperature dependences of the ethylene oxide accumulation rate in both sections of the reactor pass through a maximum. The obtained data give evidence for the occurrence of the ethylene epoxidation reaction initiated by the n-butane oxidation products under the conditions when ethylene itself is slightly oxidized.
Chemical Behaviour of CaAg2 under Ethylene Epoxidation Conditions

The binary compound CaAg2 is examined as a catalyst for the ethylene epoxidation reaction. During the induction phase, conversion and selectivity increase and then remain stable for several hundred hours. The presence of ethyl chloride as a promoter is crucial. The pristine CaAg2 reacts with the gaseous reactants and forms a porous microstructure of calcium-containing oxidation products on the surface, in which particles of elemental silver are embedded. The microstructure is remarkably stable, and in particular, prevents further sintering of the silver particles.
