Yes, INDUSTRIAL chemistry *can* use that method because... but ORGANIC chemists use this method.  Ya know why? because you dont risk BLOWING UP YOUR LAB if there is a leak if you use free radical halogenation.

It's safer to use the method that I described.  http://www.cengagebrain.com/shop/en/US/storefront/US;CMGTJSESSIONID=n69CPGBNRNk2k1w4DzMs8QHBSwqgChZr5Gb9TwXGTBqJBsYDbG70!-170442550!466608370?cmd=catProductDetail&gclid;=CLeVgvD5qq8CFSQCQAodFBylaQ&entryPoint;=storefront&ISBN;=9780840054449&cid;=GS&messageType;=catProductDetail P. 188 Organic Chemistry, 8th Edition McMurry  ISBN10: 0-8400-5444-0, ISBN13: 978-0-8400-5444-9
