I need come help on an assignment that I have to do for chemistry class. I have to write information about BHT, but its specific information. I have found most of it, but I need help on the following: the raw materials or intermediate substances from which it is made and what the manufacturing process is for BHT. If someone could just tell me or help me out. Also, is BHT produced commercially?

Thanks in advance,
