Hydroxyl bonds belong to hydroxyl endings of starch (MB, BP, BF), dihydric
Preferred alcohols are dihydric
alcohols having from two to six carbon atoms, such as 1,3-propanediol and 1,4-butanediol.

alcohols," Journal of Molecular Liquids, vol.
Phenol is monohydric and resorcinol is dihydric
The formulation contains silicone oil, volatile hydrocarbon oil, dihydric
glycol, polyoxyethylene glyceryl monoisostearate and water.
The raw material of the epoxy resin is the dihydric
phenol derivative, a white crystallization with the melting point from 174 to 175[degrees]C, which is the reaction product obtained from the dehydration condensation of vanillin and pentaerythritol.
In 2009, the total annual discharge of monohydric and dihydric
phenols into the aquatic environment was 2780 kg in Estonia, including 2260 kg in North-Eastern Estonia .
