Ethylene oxide is used directly in the gaseous form to sterilize drugs, hospital equipment, disposable and reusable medical items, packaging materials, foods and other items [SEDA, ]. A large number of samples of herbs, spices and other dried vegetables imported to Italy contained more than mg/kg of ethylene oxide (29% of 63 analysed. It is unknown whether this new ethylene demand will lead to continued investment in ethylene-derived gasoline blendstock or if it is just one-time occurrence. However, it is clear is that the surplus of ethylene production paved the way for a new source of demand.
F. Moerman, K. Mager, in Handbook of Hygiene Control in the Food Industry (Second Edition), Ethylene Oxide. Ethylene oxide (C 2 H 4 O), sometimes called oxirane, is an organic alkylating gas with very potent and highly penetrating properties. Ethylene oxide is capable of destroying most viruses, bacteria, and fungi, including bacterial spores. The important commercial applications of ethylene gas are: It inhibits the elongations of shoot and it favors’ the radial thickening of the stem. It also induces sprouting in tubers and germination of seeds. It induces fruit ripening act as ripening hormone. It increases the fruit formation.
Ethylene is a naturally occurring chemical. It comes from ripe fruit. If you grab yourself a browning banana, you will be getting a dose. Finding that out was really powerful information, Ethylene helps fruit ripen — that’s why people will tell you if you bought a rock hard avocado.

Ethylene as well as other plant growth regulators (PGRs) are important chemicals in agricultural production. Plant growth regulators are now used worldwide on a diversity of crops each year (Thomas, ). The plant hormone, C 2 H 4 strongly influences nearly every development stage in plant growth, from germination to fruit ripening and Cited by: 1.
Published October Ethylene oxide (EO) is a basic chemical produced primarily by the catalytic oxidation of ethylene. It is a chemical intermediate that cannot be directly used and is further reacted to produce a wide spectrum of products.
Ethylene Oxide. Hazard Summary. The major use of ethylene oxide is as a chemical intermediate in the manufacture of ethylene glycol. Ethylene oxide is also used as a sterilizing agent for medical equipment and a fumigating agent for spices.
The acute (short-term) effects of ethylene oxide in humans consist mainly of central nervous. Ethylene as well as other plant growth regulators (PGRs) are important chemicals in agricultural production.
Plant growth regulators are now used worldwide on a diversity of crops each year. Ethylene Oxide 1 FOREWORD Concise International Chemical Assessment Documents (CICADs) are the latest in a family of publications from the International Programme on Chemical Safety (IPCS) — a cooperative programme of the World Health Organization (WHO), the International Labour Organization (ILO), and the United Nations.
Abstract: The ethylene oxide hydration process in a catalytic fixed bed tube reactor was studied. A cross-linked styrene-divinylbenzene anion-exchange resin in the HCO 3-/CO 3 form was used as a deactivation and swelling of the catalyst during the.
Ethylene oxidation by Ag catalysts has been extensively investigated over the past few decades, but many key fundamental issues about this important catalytic system are still unresolved.
This overview of the selective oxidation of ethylene to ethylene oxide by Ag catalysts critically examines the experimental and theoretical literature of this complex catalytic system: (i) the Author: Tiancheng Pu, Huijie Tian, Michael E.
Ford, Srinivas Rangarajan, Israel E. Wachs. Uses Ethylene oxide is used as an insecticide and sterilant for a wide variety of foodstuffs. It is used mainly in vacuum fumigation mixed with different proportions of carbon dioxide or non-flammable halogenated hydrocarbons, such as dichloro-difluoromethane, to provide non-explosive conditions.
ethylene oxide in environmental media and in biological samples. The intent is not to provide an exhaustive list of analytical methods that could be used to detect and quantify ethylene oxide.
Rather, the intention is to identify well-established methods that are used as the standard methods of analysis. Many of the analytical methods used to. The below mentioned article provides a study note on the commercial uses of ethylene in plants.
Ethylene is one of the most widely used plant growth hormones in agriculture. But, due to its gaseous nature and high diffusion rate, ethylene cannot be administered to plants without confining them in closed chambers and it is very difficult to be applied in gaseous form in the.
Because of its molecular structure ethylene oxide is one of the most versatile chemical intermediates. Industrial production started in using the chlorohydrin pro- cess and was improved in by introducing the much more economic direct catalytic oxidation method.

the used and reported detection limit for ethylene oxide in EHEC is, according to the petitioner, mg ethylene oxide per kg cellulose (OFCA, ).
The same limit has been used in the screening of spices for their ethylene oxide content (Fowles et al., ). Uses of ethylene oxide-containing food additivesFile Size: KB. Restraints. The major factor restraining the growth of the ethylene market is the implementation of stringent government regulations pertaining to the production and use of ethylene.
As ethylene is combustible and carcinogenic in nature, stringent regulations on its usage. An economic analysis was performed on the ethylene plant designed, where it is expected that the plant will pro t approximately million over a 10 year operation period, with a return on investment of 16%.
It was assumed for the economic analysis that the plant will run 8, hours a year ( plant operating factor).File Size: 1MB. ¥ a water-ethylene oxide mixture with a water to ethylene oxide ratio of less than is flammable, ¥ violent polymerization of ethylene oxide can occur, releasing heat, and ¥ water is an acceptable fluid to deluge ethylene oxide vapors with, but adding water to pools of liquid ethylene oxide will cause more vapors to be released (Celanese Web).
Virtually all of the ethylene oxide produced is used as an intermediate in the production of other useful chemicals. A very important derivative is ethylene glycol which is used for the manufacture of polyester fiber for clothes, upholstery, carpet, and pillows and the blending of automotive engine antifreeze.
