The production method of this chemical is as below: Firstly. calcium carbide could react with water in the acetylene reactor to produce acetylene, and then go through washing, impurity by the sodium hypochlorite; Secondly, the purified acetylene has the complete drying and then put into the fluorination reactor; Thirdly, with the existence of sulfuryl fluoride, acetylene could react with hydrogen fluoride to produce crude Ethylidene difluoride; Lastly, go through the process of condensation, fractionation to get the products.

As to its usage, it is widely applied in many ways. It could be used as the Freon substitute, refrigerant, aerosol and so on; It could also be used as the important raw material of vinyl fluoride. Besides, it is also commonly found in electronic cleaning products, and many consumer aerosol products that must meet stringent VOC requirements.

When you are dealing with this chemical, please be more cautious. It is a kind of highly flammable chemicals which may catch fire in contact with air, only needing brief contact with an ignition source. And it has a very low flash point or evolve highly flammable gases in contact with water. Therefore, you should take the following instructions. Wear suitable protective clothing and then take precautionary measures against static discharges. Besides, keep away from sources of ignition - No smoking, and if in case of insufficient ventilation, wear suitable respiratory equipment. In addition, there is one hidden danger that is if under prolonged exposure to fire or heat, the containers may rupture violently and rocket, so you should be very careful while keeping this chemical. 
 
In addition, you could convert the following datas into the molecular structure:
(1)Canonical SMILES: CC(F)F
(2)InChI: InChI=1S/C2H4F2/c1-2(3)4/h2H,1H3
(3)InChIKey: NPNPZTNLOVBDOC-UHFFFAOYSA-N
