He aha te 2-Pyrrolidinone CAS 616-45-5?

Ko te 2-Pyrrolidinone he matū heterocyclic kei roto he hauota, he cyclic amide hoki o te waikawa gamma aminobutyric (GABA). Ka taea te mārama he mowhiti e rima ngā mema (4 ngā ngota waro me te 1 te ngota hauota) me te rōpū carbonyl (C=O). Ko te 2-Pyrrolidinone he whakarewa aprotic porowhita me te ira kohua teitei, te ira tio iti, te wairewa kaha, te pumau wera me te matū pai rawa atu.

Tono

1. Kātahi ka whakapūhuitia hei polyvinylpyrrolidone (PVP) me te polyvinylpyrrolidone (PVPP). He whānuitia te whakamahinga o ēnei polymer i roto i ngā mara pēnei i te rongoā, te kai, ngā mea whakapaipai, me ētahi atu.

2. I roto i te umanga hikohiko, te otinga tango whakaahua-ātete: Ko te 2-Pyrrolidinone he wāhanga matua e whakamahia ana i roto i te tukanga hanga o ngā semiconductors me ngā panera whakaaturanga hei tango pai me te haumaru i te whakaahua-ātete, he mea nui mō te umanga hikohiko hou. Whakamahia hei whakapai ake i te mahi pākahiko me te whakarei ake i te haumaru.

3. Nā te kaha o te wairewa, ka whakamahia ngā kaihoroi ahumahi me ngā kaihoroi peita hei hanga i ngā kaihoroi ahumahi matatau, inā koa mō te tango i ngā kapia uaua, ngā waituhi, ngā paninga, me ētahi atu.
4. Hei whakarewa matatau, ka whakamahia te waituhi me ngā paninga mō ngā waituhi motuhake (pēnei i te waituhi inkjet) me ngā paninga, kia pai ai te taurite me te pumau.

Ngā Āhuatanga

1. Wairewatanga: Ka taea te whakaranu i te 2-Pyrrolidinone me te nuinga o ngā whakarewa waro pēnei i te wai, ngā waipiro, ngā ether, ngā esters, ngā warowaihā whai kōroine, me ngā warowaihā kakara, ā, he whakarewa "ao whānui".

2. Ngā pūmau ā-tinana: Te ira kohua teitei (245 ° C), te ira tio iti (-23 ° C), te ira mura teitei (129 ° C), te pumau wera pai.

3. Ngā āhuatanga matū: He kaha ngā āhuatanga matū, ā, ka taea e ōna hononga NH me C=O te whai wāhi ki ngā tauhohenga maha.

4. Tino kaha te wairewa: Ka taea te whakarewa i ngā momo polymer, ngā kapia, ngā tae, me ngā tote kore-waro, me te whānuitanga o ngā whakamahinga.
