Salicylic acid
Salicylic acid, or ortho-hydroxybenzoic acid, is present as a white crystalline powder or in the form of white to colourless crystal needles that are sparingly soluble in cold water and slightly soluble in ethanol 96%. It is more soluble in hot water.
To prevent hardening or the formation of crystals, we recommend a double-acting mechanical seal in conjunction with a sealing pressure system (plan 53A). This ensures a constant pressure superposition.
