So embalming fluids made out of methyl alcohols instead of carcinogens like formaldehyde.

所以防腐液是用甲醇做的而不是甲醛之类的致癌。

And scientists already knew how to make it -- one way involved combining methyl alcohol and anthranilic acid, a type of acid with one of those smelly benzene rings.

已经知道如何制造它——一种方法是将甲醇和邻氨基苯甲酸结合，邻氨基苯甲酸是一种带有臭味苯环的酸。
