【摘要】 本文研究了强酸介质中尿素与甲醛的反应关系;由试验可知,其生成物与尿素和甲醛的摩尔比有很大关系。研究发现,强酸介质中,脲醛树脂的生成可缩短反应时间,节约能源。更多还原

【Abstract】 This paper dealts with the rcaction of urea to formaldehyde in a strong acid medium. The experimental results showed that the product is evidently reacted to the molar ratio between urea and formaldehyde. The ureaformalehyde resin produced in the strong acid medium allows to reduced the reaction time and save the energy.更多还原
