| Hazard Classes and Categories | Flam. Liq. 2 (100%)Flammable liquids - Category 2 |
| Skin, Eye, and Respiratory Irritations | Ethylene sulfide is ... an eye and dermal irritant. |
| Hazardous Reactivities and Incompatibilities | May polymerize violently in presence of acids, especially when warm.Reacts with 4(4´-nitrobenzyl)pyridine. |
| 処分方法 | SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air qualitypotential migration in soil or watereffects on animal, aquatic, and plant lifeand conformance with environmental and public health regulations. |
| Preventive Measures | SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place. |

使用
Ethylene sulfide is generally used in the preparation of organosulfur compounds, especially for mercaptoethylation of primary and secondary amines to obtain aminothiols.It is used in the synthesis of dendritic thioether ligands to stabilize gold nanoparticles (Au NPs).Chitosan can be chemically modified by treating ethylene sulfide to obtain a biopolymer for the removal of divalent cations from aqueous solutions.
