Claims (6)

  1. 순도가 99.5%이상인, 미량의 분순물을 함유하는 메타크릴산메틸을 설포산기 함유 화합물로 처리함을 특징으로 하는 메타크릴산메틸의 정제방법.
  2. 순도가 99.7%이상인, 미량의 분순물을 함유하는 메타크릴산메틸을 설폰산기 함유 화합물로 처리하고, 증류로 고순도 메타크릴산메틸을 수득함을 특징으로 하는 메타크릴산메틸의 정제방법.
  3. 순도가 99.5%이상이며 미량의 푸란계 화합물을 불순물로서 함유하는 메티크릴산메틸을 설폰산기 함유 화합물로 처리하여, 황산 정색법에 의한 정색이 400내지 500㎚의 파장에서 측정한 경우의 흡수 스펙트럼에서 물을 대조용으로 한 흡광도가 0.02이항인 메타크릴산메틸을 수득하는 방법.
  4. 제3항에 있어서, 푸란계 화합물이 2.5-디메틸푸란 임을 특징으로 하는 방법.
  5. 제1항 내지 제4항 중의 어느 한항에 있어서, 설폰산기 함유 화합물로서 설폰산기를 함유하는 이온교환수지를 사용하는 방법.
  6. 메타크릴산메틸 50ml에 대해 진한 황산(98%이상)5ml의 비율의 혼합물을 25℃에서 30분간 진탕혼합한후, 혼합액을 길이가 50mm인 셀에 놓고, 이의 흡수 스펙트럼을 물을 대조용으로 하여 측정하는 황산 정색법에 의한 정색이 400 내지 500㎚의 파장에서 측정한 경우의 흡수 스펙트럼에서 물을 대조용으로 한 흡광도가 0.02이하인 메타크릴산메틸 단량체.
    ※ 참고사항 : 최초출원내용에 의하여 공개하는 것임.
