Usage

Description

Vinyl chloroacetate, also known as 2-chloroethanol, is a colorless to light yellow liquid that is denser than water and insoluble in water. It has a strong irritating effect on the skin, eyes, and mucous membranes and is toxic through ingestion, inhalation, or skin absorption. It is a chemical compound with corrosive properties and is slowly hydrolyzed to produce chloroacetic acid, which has an ecological impact.

Uses

Used in Chemical Synthesis:
Vinyl chloroacetate is used as a raw material for the production of methacrylic fibers, which exhibit good affinity for acid dyes. This application takes advantage of its chemical properties to create a valuable material in the textile industry.
Used in Research and Development:
In the field of research, vinyl chloroacetate is utilized to study the effects of electron-withdrawing groups on the ligand in a series of bis(acetylacetonate)cobalt(II) derivatives. This application highlights its importance in understanding and advancing chemical reactions and compound development.
Used in Pharmaceutical Industry:
Although not explicitly mentioned in the provided materials, vinyl chloroacetate can also be used in the pharmaceutical industry as an intermediate for the synthesis of various drugs and pharmaceutical compounds due to its reactive nature and ability to form different chemical bonds.
Used in Environmental Studies:
Given its ecological impact when hydrolyzed to produce chloroacetic acid, vinyl chloroacetate can be used in environmental studies to understand the effects of chemical compounds on ecosystems and to develop methods for mitigating their potential harm.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

Vinyl chloroacetate reacts with acids to liberate heat. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides.

Health Hazard

TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Bromoacetates and chloroacetates are extremely irritating/lachrymators. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.
