Get PVC from calcium carbide. Write down 3 equations of interconversion of substances. And who knows what the formula is called: С3Н8 + Сl2⇒С3Н7Cl + HCl?
Let’s write the equations:
1. СaC2 + 2H2O = Ca (OH) 2 + C2H2 – hydration reaction, acetylene was obtained;
2. С2Н2 + HCl = H2C = CHCl – addition, chloroprene was formed;
3. nH2C = CHCl = (-H2C – CHCl-) n – polymerization, obtained polyvinyl chloride.
The reactions show a bond between alkynes and polymers, as well as a bond between inorganic and organic compounds. Polyvinyl chloride is used for the manufacture of insulating material, as well as packaging.
C3H8 + Cl2 = C3H7Cl + HCl – substitution reaction, propane chloride was formed.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
