Abstract Organic long chain binary acid solution and organic straight chain aliphatic diamine solution are mixed and reacted to produce nylon salt. The said long chain binary acid solution is obtained through solvent process of purifying termination long chain binary acid fermenting liquid; and the said organic straight chain aliphatic diamine solution is obtained by adding organic solvent which is identical to that used in the above-mentioned solvent process of purifying termination long chain binary acid fermenting liquid into straight chain aliphatic diamine. Compared with available technology, some steps are omitted and the same solvent is used, so that the present invention has simple technological process, short operation period, low power consumption and low product cost.
