ACETIC ACID with chromic acid, nitric acid, hydroxyl- containing compounds, ethylene glycal, perchloric acid, peroxides and permanganates.
ACETONE with concentrated sulphuric and nitric acid mixtures.
ACETYENE with copper (tubing), fluorine, bromine, chlorine, iodine, silver, mercury or their compounds.
AMMONIA, ANHYDROUS with mercury, halogens, calcium hypochlorite or hydrogen fluoride.
AMMONIUM NITRATE with acids, metal powers, flammable fluids, chlorates, nitrates, sulphur and finely divided organics or other combustibles.
ANILINE with nitric acid, hydrogen peroxide or other strong oxidizing agents.
BROMINE with ammonia, acetyene, butadiene, butane, hydrogen, sodium carbide, turpentine or finely divided metals.
CHLORATES with ammonia salts, acids, metal powers, sulfur, carbon, finely divided organics or other combustibles.
CHLORINE with ammonia, acetylene, butadiene, benzene, and other petroleum fractions, hydrogen, sodium carbides, turpentine, and finely divided powered metals.
CHROMIC ACID with acetic acid, naphthalene, campor, alcohol, glycerine, turpentine, and other flammable liquids.
CYANIDES with acids
HYDROGEN PEROXIDE with copper, chromium, iron, most metals or other combustible materials, aniline, and nitromethane.

HYDROCARBONS generally, with fluorine, chlorine, bromine, chromic acid, or sodium peroxide.
IODINE with acetylene or ammonia.
MERCURY with acetylene, fulminic acid, hydrogen.
NITRIC ACID with acetic, chromic and hydrocyanic acids, aniline, carbon, hydrogen suflde, flammable fluids or gases and substances which readily nitrated.
OXYGEN with oils, grease, hydrogen, flammable liquid, solids and gases.
OXALIC ACID with silver or mercury.
PERCHLORIC ACID with acetic, anhydride, bismuth and its alloys, alcohol, paper, wood, and other organic materials.
PHOSPHOROUS PENTOXIDE with water.
POTASSIUM PERMANGANATE with glycerine, ethylene glycol, benzaldehyde, sulfuric acid.
SODIUM PEROXIDE with oxidizable substances, for instance: methanol, glacial acetic acid, acetic anhydride, benzaldehyde, carbon disulfide, glycerine, ethylene glycol, ethyl acetate, furfural, etc.
SULFURIC ACID with chlorates, perchlorates, permanganates and water.

WHEN MIXING ACIDS AND WATER, POUR ACIDS INTO WATER, DO NOT POUR WATER INTO ACIDS.

Read labels. There are some of these dangerous chemicals in products that you use every day. Navel jell uses phosphoric acid. Lido weld structural adhesive has acrylic acid in it. Knowing what is in the product you're using could save you some serious problems later.

If you get the old formula book and try to use some of those exotic mixes, remember that most of the chemicals they used were low concentration and full of impurities. What you will buy is pure, and sometimes many times stronger than intended in the formula. Get your brother in law to mix the first batch. The Jim Hrisoulas books have a wonderful index that tells you the old names for modern chemicals.

Now, just because I haven't mentioned something that ends up hurting you, don't feel bad. I probably have just missed trying that trick, and will get to it eventually.
