Abstract

Se proporciona un método para elaborar lignin aminas. El método comprende proporcionar una lignina; luego modificar la lignina con un modificador para crear una lignina modificada; y luego hacer reaccionar la lignina modificada con una amina para formar una lignin amina. Los modificadores adecuados comprenden acrilatos. También se divulga un método para coagular materiales suspendidos en una corriente de agua. El método comprende proporcionar una corriente de agua y poner en contacto los materiales suspendidos en la corriente de agua con al menos una lignin amina.
