Description
PMDIの色を薄くするために、PMDAに対する特殊な追加処理〔例えば、温和な部分触媒還元(EP546400とUS5889070に記載)、再酸性化(例えば、US5386059)、特別な塩基処理(DE1 0211 021を参照)〕が提唱されている。このような追加処理は、PMDA製造プロセスの大幅に複雑化し、経済的な見地から満足できるものではない。
この目的は、少なくとも1種の溶媒の存在下における、ジフェニルメタンジアミンとポリフェニルポリメチレンポリアミンを含む対応する混合物とホスゲンとの段階的な反応によって達成され、このときホスゲン化進行の最初の段階において形成される対応した塩化カルバモイルとアミン塩酸塩において、ホスゲン化装置の次の段階を通して、塩化カルバモイルが対応するイソシアネートと塩化水素に解離し、そして幾らかのアミン塩酸塩が未反応のまま残る、ということを我々は見出した。
Claims (5)
- ジフェニルメタンジイソイアネートとポリフェニルポリメチレンポリイソシアネートとを含む混合物(ポリイソシアネート混合物)の製造法であって、
少なくとも1種の溶媒の存在下にて、ジフェニルメタンジアミンとポリフェニルポリメチレンポリアミンの混合物であって、酸触媒を用いたアニリンとホルムアルデヒドの縮合反応で得られる混合物(アミン混合物)をホスゲンと反応させる工程であって、最初の段階において、該アミン混合物から塩化カルバモイルとアミン塩酸塩が形成され、その後の段階において、該塩化カルバモイルがポリイソシアネートと塩化水素に解離し、該アミン塩酸塩がホスゲン化されて最終的にポリイソシアネートが形成される工程を含み、
残留している過剰のホスゲンが反応混合物から除去される時点において、固体アミン塩酸塩の量が10〜5000ppmであり、固体塩化カルバモイルおよび/または固体尿素が存在しない、上記製造法。 - 残留している過剰のホスゲンが反応混合物から除去される時点における固体アミン塩酸塩の残留含量が1500〜2500ppmである、請求項1に記載の製造法。
- 固体アミン塩酸塩の含量が、光散乱またはレーザーに基づく機器あるいは音波または超音波に基づく方法を使用するオンライン分析によって測定される、請求項1または2に記載の製造法。
- ポリイソシアネート混合物が、30〜90重量%のジフェニルメタンジイソシアネート異性体含量、29〜33重量%のイソシアネート含量、および25℃にて2500mPa・s以下の粘度を有する、請求項1〜3のいずれか一項に記載の製造法。
- ホスゲンとの前記反応に引き続いて、反応生成物から過剰のホスゲン、塩化水素、および溶媒を分離する、請求項1〜4のいずれか一項に記載の製造法。
