  • Process for isolation of an organic amine
    Patent number: 7977514
    Abstract: The invention relates to a process for the isolation of an organic amine from a composition comprising the organic amine and an acid, or a salt of the organic amine and the acid, wherein the process comprises steps wherein ammonia or hydrazine is added to the composition thereby forming a multi-phase system comprising an organic amine-rich phase and an acid-rich phase, the organic amine-rich phase and the acid-rich phase obtained in step (i) are separated, and the organic amine is isolated from the organic amine-rich phase.

  • Process for recovering and recycling polyamide from carpet waste
    Patent number: 5840773
    Abstract: The present invention relates to a process for treating polyamide-containing carpet waste by extracting the polyamide from the carpet waste with an extraction agent containing an aliphatic alcohol. The separated polyamide can then be recovered from the extract and recycled for further use. In addition, carpet waste containing two polyamides can be treated in accordance with the present invention so as to separately recover each polyamide. The process according to the present invention provides a high yield of the polyamide. The presence of other constituents normally present in carpets does not interfere with the separating and recycling of the polyamide.
