Kaihanga Utu Pai Methylene Chloride CAS: 75-09-2

whakaahuatanga poto:

Ko te Methylene Chloride he matū i hangaia e ngā ngota hauwai e rua i roto i ngā ngota methane, me te ngota CH2CL2. He wai kore tae te Methylene Chloride, he mārama, he taumaha, he pūngāwerewere. He kakara me te reka rite ki te ether. Kāore e mura. He paku wairewa te Methylene Chloride ki te wai, ā, ka rewa ki ngā whakarewa rauropi e whakamahia whānuitia ana. Ka taea hoki te rewa i roto i tētahi ōwehenga me ētahi atu whakarewa kei roto he chlorine, te ether, te etanoru, me te N-di metamimamamide. He uaua te rewa o te Methylene Chloride ki te haukini wai i te pāmahana rūma, ka taea te rewa tere ki roto i te phenol, te aldehyde, te ketone, te triathrin, te tororine, te cycamine, te acetylcetate. Ko te āhua Chemicalbook he 1.3266 (20/4 ° C). Ko te ira rewa -95.1 ° C. Ko te ira kohua 40 ° C. He maha ngā wā ka whakamahia ngā whakarewa ira kohua tino iti hei whakakapi i te petroleum ether mura, te ether, me ētahi atu, ā, ka taea te whakamahi hei rongoā whakangote ā-rohe, hei whakamatao me hei kai tinei ahi. Ko te pūwāhi mura ohorere ko 640 °C. Ko te wai whakapūkara (20 °C) 0.43MPa · s. Ko te taupū whakaata (20 °C) 1.4244. Ko te pāmahana matua ko 237 °C, ā, ko te pēhanga matua ko 6.0795MPa. Ka puta te HCL me ngā tohu mārama i muri i te wai whakapūkara, ā, ka whakamahanahia te wai mō te wā roa hei whakaputa i te formaldehyde me te HCL. Ka taea hoki te tiki i te chloride, CHCL3 me te CCL4.

Whakaahuatanga

Ngā Āhuatanga: Kāore he pūmahana mura o te dichloromethane parakore, ā, kāore e mura te ranunga whakarewa kei roto he rahinga ōrite o te dichloromethane me te penehīni, te naphtha whakarewa, te toluene rānei. Heoi, ina konatunatua te dichloromethane ki te acetone, ki te methanol rānei i te ōwehenga 10:1, ka puta he pūmahana mura, he mamaoa, he hau hei hanga i tētahi ranunga pahū, ko te rohe pahū he 6.2% ~ 15.0% (rahinga).

Ngā Whakamahinga o te Methylene Chloride

He kaha te wairewa o te Methylene Chloride (DCM) me te iti o te paitini. Ka whakamahia hei hanga kiriata haumaru me te polycarbonate, ā, ko te toenga ka whakamahia hei whakarewa paninga, hei tango whakarewa, hei rehu paowa hau, hei pahuka polyurethane, hei tango pokepokea ai te kino, hei kaihoko peita. He wai kore tae te Dichloromethane, e whakamahia ana hei reo tauhohenga i roto i te umanga rongoā hei whakarite i te ammonia penicillin, hydroxycin me te pioneecin, me ētahi atu; hei hanga i ngā kaihoko tango hangai rauropi, polyurethane me ētahi atu kirihou pahuka hei hanga i ngā kaihoko pahuka me ngā kaihoko horoi whakarewa. Ko te nuinga o te whakamahinga o te Dichloromethane i roto i te mara o te hanga kiriata me ngā rongoā i Haina. I roto i ēnei, ko te whakamahinga o te hanga kiriata e 50% o te katoa o te whakamahinga, ko te rongoā e 20% o te katoa o te whakamahinga, ko te whakamahinga o te kaihoko horoi me te umanga matū e 20% o te katoa o te whakamahinga, ā, ko ētahi atu āhuatanga e 10%. Ka whakamahia hoki te Dichloromethane i roto i ngā pūnaha whakamatao ahumahi hei whakamatao, engari he tino kino, ā, ka taea te whakaputa i te mārama paitini ina pa atu ki te ahi mārama, ki ngā mea e mura ana rānei. Mō te hau makuku, ka taea te whakamahi i te hauwai pūhaumāota kua waikuratia hei whakatairanga i te hauwai pūhaumāota, ā, ka taea hoki e te mārama te whakatairanga i te waikura me te whakarei ake i te konganuku waikura. Whakamahia mō te whakamatao i te whakamomona witi me ngā taputapu tio me te hauhautanga ngaohiko iti. I roto i te hanga kirihou alkane mimi momo polyether, ka whakamahia hei kaihoko pupuhi āwhina, me ngā kaihoko pupuhi hoki mō te pēhi i ngā kirihou pahuka polymutra. Ka whakamahia hoki te dichloromethane hei hanga matū mō te kawhe maroke. Ka tunua tuatahi te kawhe hei whakarewa i te kawheine ka mānu i runga i te mata, kātahi ka whakamahia te dichloromethane hei tango i te kawheine.
