Abstract
A long-chain composition has at least one long-chain alkane selected from the group consisting of C9-18 linear or branched alkanes and at least one long-chain carboxylic acid selected from the group consisting of C9-18 linear or branched, saturated or unsaturated aliphatic monocarboxylic acids. The mass ratio of the long-chain alkane to the long-chain carboxylic acid ranges from 1:1 to 40:1. The long-chain composition has a higher fermentation degree or higher substrate utilization rate and the like, when used as a starting material in the production of long-chain dibasic acids via fermentation.
Claims9
A long-chain composition, comprising at least one long-chain alkane selected from the group consisting of n-dodecane, n-tetradecane, and n-hexadecane and at least one long-chain carboxylic acid selected from the group consisting of lauric acid, myristic acid, and palmitic acid, wherein the long-chain alkane and the long-chain carboxylic acid have the same number of carbon atoms, and the mass ratio of the long-chain alkane to the long-chain carboxylic acid ranges from 2:1 to 20:1, and the long-chain composition further comprises water and has a pH value ranging from 7.5 to 10, and the mass of the water is 0.5 to 10 times the sum of the mass of the long-chain alkane and the mass of the long-chain carboxylic acid.
