p-Toluenesulfonic acid (PTSA or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH₃C₆H₄SO₃H. It is a white extremely hygroscopic solid that is soluble in water, alcohols, and other polar organic solvents. The CH₃C₆H₄SO₂ group is known as the tosyl group and is often abbreviated as Ts or Tos.

Diethanolamine is polyfunctional, being a secondary amine and a diol. Like other organic amines, diethanolamine acts as a weak base. Reflecting the hydrophilic character of the secondary amine and hydroxyl groups, DEA is soluble in water. Amides prepared from DEA are often also hydrophilic.

Lactic acid is an organic acid. It has a molecular formula CH₃CHCOOH. It is white in the solid state and it is miscible with water. When in the dissolved state, it forms a colorless solution. Production includes both artificial synthesis as well as natural sources.

Acetonitrile is used mainly as a solvent in the purification of butadiene in refineries. Specifically, acetonitrile is fed into the top of a distillation column filled with hydrocarbons including butadiene, and as the acetonitrile falls down through the column, it absorbs the butadiene which is then sent from the bottom of the tower to a second separating tower. Heat is then employed in the separating tower to separate the butadiene.

ETPI is a quaternary phosphonium salt mainly used for the advancement and / or curing of phenolic based epoxy resins and thermosetting powder coatings. It can also be used in organic synthesis as a wittig reagent and as a phase transfer catalyst in the production of fluoroelastomers .

Hydroxybenzotriazole (abbreviated HOBt) is an organic compound that is a derivative of benzotriazole. It is a white crystalline powder, which as a commercial product contains some water (~11.7% wt as the HOBt monohydrate crystal). Anhydrous HOBt is explosive.
