Description
本発明の一実施形態によれば、第１のスラリーを加熱するステップは、硫酸の添加を全く含まない。しかし、本方法は、第１のスラリーを転換するステップ中に、上記第１のスラリーへの硫酸を添加してもよい。しかし、硫酸の添加量は、第２のスラリーをろ過した後の生成リン酸が、２重量％未満、好ましくは０．０５〜１．５重量％程度、特に、０．０５〜１重量％未満程度の遊離ＳＯ３含量を含有するように厳密に計量すべきである。硫酸により、上記生成リン酸が、リン酸としての使用に適さなくなり、硫酸除去ステップが必要にならないように、リン酸を硫酸によって汚染しないようにこの含量を超えないことが重要である。
Claims (1)
- 第１のスラリーを転換するステップ中に、硫酸の第１のスラリーへの導入を含むことを特徴とする、請求項１及び２のいずれか一項に記載の方法。
