Whakatakotoranga Methylparaben
Ko te Methylparaben, me te nama rēhita CAS 99-76-3, e mōhiotia ana ko te Methyl p-hydroxybenzoate; 4-(Methoxycarbonyl)phenol. Nō roto i ngā kāwai hua o te Developer; Functional Materials; Aromatics. Ko tōna nama EINECS ko 202-785-7. Ko te tātai ngota o tēnei matū ko C8H8O3ā, ko te taumaha ngota he 152.15. Heoi anō, ko tōna ingoa pūnaha ko te waikawa Benzoic,4-hydroxy-,methyl ester. Ka mimiti wawe te Methylparaben mai i te ara kai, mā te kiri rānei. Ka waikurahia hei waikawa p-hydroxybenzoic, ā, ka tere te tukuna atu me te kore e kohikohi ki roto i te tinana. I roto i te taupori he kiri noa, kāore te methylparaben e whakapataritari, kāore hoki e whakararuraru; heoi, kua pūrongohia ngā mate pāwera ki ngā parabens kua kainga. Ka kitea i roto i te maha o ngā hua kiri/kanohi matua.
Ko ngā āhuatanga ā-tinana o Methylparaben ko: (1)ACD/LogP: 1.882; (2)# o te Ture 5 Ngā Takahi: 0; (3)ACD/LogD (pH 5.5): 1.88; (4)ACD/LogD (pH 7.4): 1.83; (5)ACD/BCF (pH 5.5): 15.83; (6)ACD/BCF (pH 7.4): 14.11; (7)ACD/KOC (pH 5.5): 251.25; (8)ACD/KOC (pH 7.4): 223.85; (9)#Ngā kaiwhiwhi here H: 3; (10)#Ngā kaituku here H: 1; (11)#Ngā Here Hurihuri Noa: 3; (12)Taupū o te Whakaata: 1.547; (13)Te Whakaata ira: 39.908 cm3; (14)Rōrahi Mīra: 125.756 cm3; (15)Taumahatanga o te Mata: 45.7929992675781 dyne/cm; (16)Kōmatotanga: 1.21 g/cm3; (17)Ira Uira: 116.398 °C; (18)Enthalpy o te Whakakohu: 52.377 kJ/mol; (19)Ira Kohua: 265.536 °C i te 760 mmHg; (20)Pēhanga Kohu: 0.00600000005215406 mmHg i te 25°C;
Ngā Whakamahinga o te Methylparaben: E mōhiotia ana ka taea e te Methylparaben te whakaroa i te tere tipu o te Drosophila i ngā wāhanga torongū me ngā wāhanga kōpura. He rongoā harore e whakamahia whānuitia ana hei tiaki kai, rongoā, me ngā mea whakapaipai. Ko te Mycocten, ā, e whakamahia whānuitia ana hei rongoā ārai-harore i roto i ngā rauemi kai a te Drosophila. Ko te Methylparaben he rongoā ārai-harore e whakamahia pinepinetia ana i roto i ngā hinu makawe. He maha ngā wā ka kitea te matū i roto i ngā carpules o te rongoā whakamoe ā-rohe, e mahi ana hei rongoā ārai-bacteriostatic me te tiaki. Ko te Methylparaben (e kiia ana ko Nipigin M, Tegosept, me Mycocten) e whakamahia whānuitia ana hei rongoā patu harore i roto i ngā rauemi kai a te Drosophila. E mōhiotia ana ka taea e te whakamahinga o te methylparaben te whakaroa i te tere tipu o te Drosophila i ngā wāhanga torongū me ngā wāhanga kōpura.
He kino te Methylparaben ina manawahia, ina pā ki te kiri, ā, ki te horomia hoki. He mea whakapataritari ki ngā kanohi, ki te pūnaha manawa me te kiri. Ina whakamahia, kakahuria he kākahu tiaki tika, ā, karohia te pā ki te kiri me ngā kanohi. Mēnā ka pā ki ngā kanohi, horoia tonutia ki te nui o te wai, ka rapu tohutohu hauora.
