     	본 발명의 폐 폴리에틸렌 테레프탈레이트로부터의 테레프탈산과 에틸렌글리콜의 연속 제조방법은 1) 용융 폴리에틸렌 테레프탈레이트와 물을 혼합하여 온도 280∼450℃, 압력 10∼35 MPa에서 폴리에틸렌 테레프탈레이트를 가수분해시키는 단계와; 2) 가수분해된 반응 생성물에 암모니아수를 투입하여 생성물중 테레프탈산을 용해시키고, 녹지 않는 불순물을 제거하는 단계와; 3) 불순물이 제거된 테레프탈산-에틸렌글리콜-암모니아수 용액에 산 용액을 투입하여 테레프탈산을 석출시켜 분리해내는 단계; 및 4) 테레프탈산이 석출된 암모늄염 용액에서 에틸렌글리콜을 분리해내는 단계를 포함한다.

Abstract: 본 발명은 내부에 ICC가 내장된 이동 통신 단말기에 있어서, 상기 ICC에 충전기플러그를 삽입할 수 있도록 삽입부가 형성되고, 상기 삽입부의 내부 상단 양측에는 제1걸림공이 구비되며, 상기 삽입부의 하단 양측에는 제2걸림공이 형성된 케이스와; 상기 케이스의 제1걸림공과 제2걸림공에 회전 가능하게 결합되도록 상단 양측에는 제1걸림돌기를 형성한 제1도어와 하단 양측에는 제2걸림돌기를 형성한 제2도어로 구성되는 한조의 도어 및; 상기 도어의 양측에 형성된 걸림돌기 중 일측에 결합되어 도어에 탄성력을 부여하는 탄성부재를 포함하여 구성되어 내부로  먼지 등의 이물질의 투입을 방지하고, 배터리의 충전시에는 충전기 플러그를 밀어 넣는 것에 의해 도어가 열리면서 ICC에 결합되어 충전기 플러그의 탈부착 용이성이 커지게 될 뿐만 아니라, 이를 통하여 종래와 같이 보호캡의 분실 또는 열화를 방지할 수 있게 됨은 물론, 케이스의 외부에 도어가 돌출되지 않기 때문에 단말기의 미려함을 향상시킬 수 있는 이동 통신 단말기의 ICC 보호장치를 제공한다.
