Dimethyl: oko kukuthi, kwezinye iimeko, isetyenziswa. Analogs nengxelo kuthetha

Namhlanje, kukho amachiza amaninzi nokubola. Kulo mzekelo, isixhobo efanayo, kodwa abantu ahlukileyo kunokuba zombini ukubonisa ukusebenza eliphezulu kwaye ayiniki ngokupheleleyo ziphumo. Konke oku kuxhomekeke kumntu ngamnye kunye neengxaki zakhe. Kodwa kukho isixhobo oko kumlungele na phantse wonke. Le nto yaziwa ngokuba dimethyl phthalate. Loo nto ke, kwezinye iimeko, nokuba isetyenziselwa kwaye akukho imiphumela emibi? Iimpendulo zale mibuzo neminye iya kuphendulwa kwinqaku.

ulwazi jikelele

Ngoko ke, siya kugxininisa kulo mba dimethyl phthalate. Yintoni na? Eli candelo esebenzayo enoku ukwakheka dimethyl utywala O-phthalic acid yayo.

Ngaphandle kuthetha ibonakala kulwelo enemibala emihle, kwaye nevumba elimnandi. Le into ayiqondakali enyibilikayo emanzini kunye neeoyile, kodwa enyibilikayo utywala.

Dimethyl phthalate ethengiswa ekhemesti, impahla yendlu, kunye noovimba yezilwanyana. Kokuba zimelwe ngohlobo kwesisombululo, amafutha okanye ntlama. Kuxhomekeke kuya kuba ezahlukeneyo, kwaye ixabiso lemali - ukusuka engange-50 ukuya 500 pack ngamnye (ityhubhu, ibhotile).

isicelo

Dimethyl phthalate (oko kukuthi, kakade) ungasetyenziswa amayeza yoluntu lwezilwanyana.

Kuba izilwanyana asisetyenziswa njenge arhente yokhuselo kwisifo samakhalane, iingcongconi, iintakumba, horseflies, midges kunye nezinye izinambuzane.

Abantu basebenzisa ngayo njengenye yeekhomponenti abangabancedani ukuba ziyisebenzise mkhuhlane, kwakunye nokuthintela iluma tick.

Izimo

Kukho ezinye iimeko apho zithintelwe ngokungqongqo ukusetyenziswa dimethyl phthalate. An amafutha, isicombululo, kunye naluphi na olunye uhlobo iindlela ingenakusetyenziswa kulophulo abantwana, kwakunye abasetyhini abakhulelweyo kunye nabongi. Oku kungenxa ithuba kwezinto kuchaphazela kakubi DNA yomntu.

Ngoko ke, ngoku kukho uphuhliso olusebenzayo izixhobo ezifanayo eziya kuba ezi Izimo.

imithetho isicelo

Dimethyl kufuneka isicelo ukuya kummandla ochaphazelekayo ulusu abezichubile kwaye ndawo ngeenxa zonke kuyo. zinokugutyungelwa ukuze ukuphumeza ukusebenza ngendlela nangakumbi uboya bayo, ubeke phezu iikawusi okanye bandage acocekileyo.

Kuthetha ngendlela kwesisombululo isicelo kwi lesikhumba isiqwenga cotton wool. Emva kokuba inkqubo kufuneka ukuba uhlambe izandla zakho kakuhle.

Ukuba kweziyobisi kwiinwebu yi ukhawulezise kangangoko unakho ukususa phantsi umsinga wamanzi ashushu nabandayo.

imiphumela emibi

phthalate Dimethyl lulwelo zinetyhefu esezantsi, kwaye xa isetyenziswa kakuhle kunqabile kakhulu uba unobangela neziphumo ebezingalindelekanga. Ukusabela okunge- omzimba kwezinye iimeko ngazo kuphela ngokwayo ngohlobo ukusabela komzimba: irhashalala kunye ukurhawuzelela. Xa kusenzeka, kubalulekile ukuba ukuhlamba off imveliso kunye nesikhumba. Ukongeza, kucetyiswa reception iziyobisi antiallergic azipilisi okanye aqholiweyo.

analogs

Ngaba Ndiyibuyisela into dimethyl? Analogs kuthetha ezikhemisti, kodwa iya kwahluka kumafa yayo kwaye ikakhulu into esebenzayo. Le ngaphandle kuphela repudin nayo iqulethe ukwakheka dimethyl utywala O-phthalic acid yayo.

Substances ukuba kungathathwa lihambisana dimethyl phthalate - mathumbu kunye plasticizer.

phthalate Dimethyl imithi abantu

Siye bahlola phthalate kweziyobisi dimethyl. Ukuba sele yaziwa, kuyimfuneko ukwazi uncedo lusetyenziswa njani na amayeza abanam. Imithi oluqhelekilyo unyango lwe ngundo.

Kufuneka ezixutywe bayalingana phthalate dimethyl, iqanda ekrwada, ioli kajongilanga kunye acetic acid. Lo mxube kubangele ebusuku isicelo eluswini, wambu itawuli yephepha perebintovyvayut. Ukuze ube kakhulu ngempumelelo ufuna ukwenza i greenhouse effect ngokuyambathisa engxoweni yeplastiki. Ezinye imaski kufuneka kugcinwe efrijini.

Isigqumathelo has a kahle eliphezulu, yaye ibonisa elihle sele emva kweveki enye isicelo.

Izimvo zezithuthi

Yintoni abaxhasi uthini indawo dimethyl? Analogs kunye into ezingundoqo kakhulu kakuhle kwakhona ezininzi abantu kulo ndawo.

Ichiza uyasokola ngokugqibeleleyo ngulo mngundo eluswini, ingakumbi ukuba kusetyenziswa kubanjiswene namanye amacandelo unyango udibaniso. Njengoko ncomo, emva kweentsuku ezimbalwa usebenzisa indlela amabala shwaka, ukurhawuzelela, baqhumisela imvakalelo kummandla ochaphazelekayo. Kodwa emva kwethutyana ingxaki ubalekela ngokupheleleyo.

ukusebenza High iindlela esizibonakalisa zokuzikhusela izinambuzane akukho kuphela izilwanyana kodwa ebantwini.

Kodwa kukho ezinye downsides.

Okokuqala, i-arhente iyasebenza ekulweni ngundo kuphela njengesakhi nkarhinyana. Akhululwayo wazikhuphulula kwezo ngxaki, ngelishwa, akakwazi. Ngoxa ekuhlangabezaneni kakuhle kakhulu nokuphelisa iimpawu.

Okwesibini, fumana dimethyl ukuthengiswa kunzima, ekubeni kwandile. Kodwa ke, ngenxa ukusebenza kwayo, kufuneka ufumane ixesha abanye ukuba bafune kuye.
