||resorcinol technical grade
Resorcinol crystallizes as colorless needles which are readily soluble in water, alcohol, acetone and ether, but almost insoluble in chloroform, benzene and carbon disulfide.
Resorcinol possess phenol properties. Being treated with halogens gives corresponding 2,4,6-trihalogen derivatives. With concentrated nitric acid, in the presence of cold concentrated sulfuric acid, it yields trinitro-resorcin (styphnic acid). Reaction with aldehydes produces resorcinol aldehyde resins.
