Chloroform (CHCl3) is made by taking methane adding chlorine and then heating the compound up until between 400 and 500 degrees Celsius. Methane (CH4) can be obtained from manure from animals when the manure ferments over time. Chlorine gas (Cl2) was invented in week 4. The chemical formula for this is:


CH4 + Cl2 CH3Cl + HCl


After this, you take the CH3Cl, or chloromethane, and repeat the process with the chloromethane instead of the methane. This causes the products to contain progressively more chlorine:


CH3Cl + Cl2 CH2Cl2 + HCl


Then repeat the process again using dichloromethane, and then chloroform respectively:


CH2Cl2 + Cl2 CHCl3 + HCl

CHCl3 + Cl2 CH4 + HCl


The products formed are: chloromethane, dichloromethane, chloroform, and carbon tetrachloride. They are then separated by distillation.


The use of chloroform that would be most beneficial would be in a pharmaceutical sense where it can be used to extract or purify antibiotics and can be used to help product pesticides and dyes.
