  A salt-splitting liquid (SSL) and a process that uses the SSL to "split" (alkyl)ammonium 3-hydroxypropionate salts into ammonia (or amines) and 3-hydroxypropionic acid (3-HP) that minimizes increases in viscosity and condensation reactions of the 3-HP. Converting (alkyl)ammonium 3-hydroxypropionate in an aqueous mixture to 3-HP includes admixing a polar aprotic organic solvent and an azeotroping solvent with the aqueous mixture. The azeotroping solvent forms an azeotrope mixture with water of the aqueous mixture. The SSL is heated to convert the (alkyl)ammonium 3-hydroxypropionate to 3-HP and ammonia, where heating produces a vapor phase containing at least water, ammonia and the azeotroping solvent. At least a portion of the water and the ammonia is removed from the vapor phase during the heating, and at least a portion of the azeotroping solvent is returned from the vapor phase back to SSL to maintain the azeotrope mixture with the water.

  一种盐分离液（SSL）和使用SSL的过程，用于将（烷基）氨基丙酸盐分解成氨（或胺）和3-羟基丙酸（3-HP），以最小化粘度增加和3-HP的缩合反应。将（烷基）氨基丙酸盐在水混合物中转化为3-HP包括将极性无电子对供体有机溶剂和共沸溶剂与水混合物混合。共沸溶剂与水形成共沸混合物。加热SSL将（烷基）氨基丙酸盐转化为3-HP和氨，加热产生至少含有水，氨和共沸溶剂的蒸汽相。在加热过程中，至少部分水和氨从蒸汽相中去除，并将至少部分共沸溶剂从蒸汽相返回到SSL中，以维持与水的共沸混合物。
