75-38-7

1,1-DIFLUOROETHYLENE(75-38-7) (or vinylidene fluoride) is a colorless gas which is flammable in the ranges of 5.5 to 21%. 1,1-DIFLUOROETHYLENE(75-38-7) is toxic by inhalation and contact. 1,1-DIFLUOROETHYLENE(75-38-7) is slightly soluble in water and soluble in alcohol and ether. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket.

1,1-DIFLUOROETHYLENE is sensitive to heat. This compound is incompatible with oxidizers. 1,1-DIFLUOROETHYLENE can react violently with hydrogen chloride. Alkyl boron and alkyl hyponitrite compounds initiate polymerization. 1,1-DIFLUOROETHYLENE will form peroxides on exposure to pure oxygen. .

Highly flammable. Slightly soluble in water.

Vapors may cause dizziness or asphyxiation without warning. Some may be toxic if inhaled at high concentrations. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating and/or toxic gases.

Vinylidene fluoride is used in the formulation of many polymers and copolymers, such as chlorotrifluoroethylene-vinylidene fluoride (Kel F), perfluoropropylene-vinylidene fluoride (Viton, Fluorel); polyvinylidene fluoride; and hexafluoropropylene-tetra-fluoroethylene- vinylidene fluoride; elastomeric copolymers. It is also used as a chemical intermediate in organic synthesis. NIOSH has estimated 32,000 workers are exposed annually.

EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Silane will ignite spontaneously in air. May polymerize explosively when heated or involved in a fire. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Cylinders exposed to fire may vent and release flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket.

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 20 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. If frostbite has occurred, seek medical attention immediately; do NOT rub the affected areas or flush them with water. In order to prevent further tissue damage, do NOT attempt to remove frozen clothing from frostbitten areas. If frostbite has NOT occurred, immediately and thoroughly wash contaminated skin with soap and water.

UN1959 Vinylidene fluoride shipped as 1,1-Difluoroethylene or Refrigerant gas R-1132a, Hazard Class: 2.1; Labels: 2.1-Flammable gas. Cylinders must be transported in a secure upright position, in a well-ventilated truck. Protect cylinder and labels from physical damage. The owner of the compressed gas cylinder is the only entity allowed by federal law (49CFR) to transport and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express written permission of the owner.

idizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, aluminum chloride. Capable of forming unstable peroxides, which can cause explosive polymerization. It can re act violently with hydrogen chloride. Alkyl boron and alkyl hyponitrite compounds initiate polymerization. It will form peroxides on exposure to pure oxygen. May accumulate static electricity, and cause ignition of its vapors.

Colorless gas; faint ethereal odor. Slightly soluble in water; soluble in alcohol and ether.

Vinylidene fluoride is a colorless gas. Faint ethereal odor. Shipped as a liquefied compressed gas.

Return refillable compressed gas cylinders to supplier.

ChEBI: Vinylidene fluoride is an organofluorine compound and an olefinic compound.

Oxidative metabolism of 1,1-Difluoroethylene is mediated by the hepatic microsomal monooxygenase to form epoxide and the inactivation of hemeprotein.

1,1-Difluoroethylene is a colorless gas. It is slightly soluble in water, but soluble in organic solvents such as alcohol and ether. Its boiling point is -85°C, melting point is -144°C, specific gravity is 0.617 g cm^-3, and vapor pressure is 3.0×10⁴ mm Hg. Its octane/water partition coefficient is 1.24 and Henry’s law constant is 0.4 atm-m³ mol^-1.
Production and use of 1,1-Difluoroethylene result in its release to the environment through various waste streams. It has medium mobility in soil and degrades in soil. It volatilizes from the contaminated water. Aquatic bioconcentration and adsorption to sediment are not very significant. As a gas form in the atmosphere, it reacts with photochemically produced hydroxyl radicals and degrades.
