摘要： The present invention provides a boron-containing synergistic urea and preparation method and application thereof, the boron-containing synergistic urea is a product obtained by mixing, dehydrating and pelletizing a mixed aqueous solution of polyaspartic acid chelated potassium (also referred to as “polypeptide chelated potassium”) and a borate amine salt together with molten urea, wherein the above three components are 0.04-0.12%, 0.08-0.24% and 99.64-99.88% by weight, respectively. The boron-containing synergistic urea provided by the present invention is obtained by effectively compositing polypeptide acid chelated potassium, borate amine salt and urea, which also can guarantee the application amount of effective boron, and meanwhile can help avoid excessive high local concentrations of boron, and achieve the purposes of prompting effective absorption of the plant to boron and of improving urea utilization rate.
摘要翻译：本发明提供含硼协同尿素及其制备方法和应用，含硼协同尿素是通过将聚天冬氨酸螯合钾（也称为“多肽螯合的”）的混合水溶液混合，脱水和造粒得到的产物钾“）和硼酸盐盐以及熔融尿素，其中上述三种组分分别为0.04-0.12％，0.08-0.24％和99.64-99.88％（重量）。本发明提供的含硼协同尿素是通过有效合成多肽酸螯合钾，硼酸胺盐和尿素得到的，这也可以保证有效硼的使用量，同时可以有助于避免硼的过量高的局部浓度，达到促进植物有效吸收硼的目的，提高尿素利用率。

摘要： The present application provides a preparation method of a formamide compound, the preparation process includes: uniformly mixing raw material of methanoic acid and an amine compound selected from a primary amine or a secondary amine to prepare a homogeneous reaction system; the above homogeneous reaction system is heated to 160-230° C., allowing carbon monoxide to be decomposed from the homogeneous reaction system and participates in the reaction, and collecting the reaction product to obtain a formamide compound. The present application provides a new technology using a homogeneous method to synthesize a formamide compound, the reaction process needs no use of a catalyst, the operation process is simple and controllable, and the raw material of the amine compound has a high selectivity.
