Title:
HIGH-CARBON CHAIN ALKANE DIAMINE, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/093949
Kind Code:
A1
Abstract:
The present invention relates to the field of high-carbon chain alkane diamine preparation, and disclosed thereby are a high-carbon chain alkane diamine, a preparation method therefor and an application thereof. The preparation method for a high-carbon chain alkane diamine as described in the present invention is characterized in that the structure of the high-carbon chain alkane diamine is represented by the formula NH2-(CH2)m-NH2; the method comprises the following steps: 1) under amidation reaction conditions, reacting a high-carbon chain alkane diacid represented by the formula COOH-(CH2)n-COOH with an ammonia-containing compound to obtain a high-carbon chain diamide represented by the formula CONH2-(CH2)n-CONH2; 2) under basic conditions, in the presence of water, sodium hypochlorite and/or sodium hypobromite, causing the high-carbon chain diamide represented by the formula CONH2-(CH2)n-CONH2 to undergo a rearrangement and degradation reaction to obtain a high-carbon chain alkane diamine represented by the formula NH2-(CH2)m-NH2, wherein n=9-13 and m=9-13. The method of the present invention is a safe, convenient, simple, and easy-to-implement method for preparing a high-carbon chain alkane diamine.
