N - (n-butil) thiophosphoramide alcohol (NPT) and urea fertilizer, ammonia alcohol solution used as urea inhibitor

摘要

It refers to a method designed to reduce the volatility of urea fertilizer, which includes dissolving triethylamine n - (n-butil) - sulfur phosphorus (NPT) into amino alcohol containing 1 - (H) x-n - ((CH2) M-OH) n Formula 1 - (H) x-oh) n, When x is 1 and 3, when x is 0, n is 2, or 2 - (H) and - N - (CH2) - choh-ch3) Z, so that the length of the carbon chain where the dihydroxy group is located is 3, or 0 or 1, while Z is 2, when y is 1, when y is 3, when y is 0, the NPT solution is formed, and urea fertilizer is combined with particles or liquid.
