UTSHINTSHO LWEENCWADI LOMSEBENZI

Intshayelelo

I-phenoxyethanol, isetyenziswe ngokugcina ngokubanzi kwi-cosmetics, ifumene udumo ngenxa yokusebenza kwayo ngokuchasene nokukhula kwe-rotional kunye nokuhambelana neminyhafu yolusu. Ngokwesiko alwenziwe nge-Williamson Ether Synthesis usebenzisa i-sodium hydroxide njengeyona nto ibaluleke kakhulu, inkqubo ihlala ijongene nemiceli mngeni efana nokwenziwa kwendalo, kunye neenkxalabo zokusingqongileyo. Inkqubela phambili yamva nje kwiChemastry ye-Catalytic kwaye ubunjineli obulihlaza buyivule i-Noveltay yeNovel: Indlela ethe ngqo ye-Ethyylene oxide ne-phenol ye-phenol ivelise i-pinol yenqanaba eliphezulu, iBakala le-cosmetic. Oku kuthembisa okungenazinto zibalulekileyo ukuchaza ngokubhala imigangatho yemveliso yemveliso ngokuphucula uzinzo, ukukhululeka, kunye nokusebenza ngendleko.

Imiceli mngeni kwezi ndlela ziqhelekileyo

I-cynthesical synthesis ye-phenoxitthanol ibandakanya impendulo ye-phenol nge-2-chloroethanol kwiimeko ze-alkaline. Ngelixa isebenza, le ndlela ivelisa i-sodium hloride njenge-byproduct, ifuna ukucacisa okuninzi. Ukongeza, ukusetyenziswa kwe-therincated kuphakamisa iinkxalabo zendalo esingqongileyo kunye nezokhuseleko, ngakumbi ngokuhambelana ne-cosmmetics yeshishini lemizi-mveliso kwi "mveliso" yeGreen ". Ngapha koko, ukulungiswa okungahambelaniyo nokungahambelani okukhokelela kwimpumlo ye-Polythyethylene Glyol Derivatives, ethobela imveliso yomgangatho kunye nokuthotyelwa kwemveliso.

Ubugcisa betekhnoloji

Ukuqhekeka kulele kwinkqubo yamanqanaba amabini afanelekileyo esusa i-regentan ekhutshiweyo kwaye inciphise inkunkuma:

Ukusebenza kwe-Epoxide:I-Ebanonene Oxide, i-EPOXID esebenzayo kakhulu, ivuleka i-ring-evula i-ring bukho kwi-phenol. I-Novel Hoterogeonet Catatalyst (umz., U-Zeolite-oxhasa i-Sulfonic Acid) eqinisekisa eli nyathelo liphantsi kwamaqondo obushushu obumlimo (i-60-80 ° C), ukuphepha iimeko ezinzulu.

Ukukhetha i-etheriyariting:I-Catalyst iyalela ukuphendula kwi-phenoxitthanol ngelixa icinezela i-Polymerization Reaction Reaction. Iinkqubo zolawulo lwenkqubo eziPhambili, kubandakanya itekhnoloji ye-Microreactoc, qinisekisa ubushushu obuchanekileyo kunye nolawulo lwesisele, ukufezekisa> Amaxabiso okuguqula ama-95%.

Izibonelelo eziphambili zendlela entsha

Ukuzinza:Ngokutshintsha i-plarinurs precurs kunye ne-e-ithylene oxide, inkqubo isuse imijelo yenkunkuma enobungozi. Ukuphindaphindwa kwenkuthazo kunciphisa ukusetyenziswa kwezinto, ukulungelelaniswa neenjongo zoqoqosho ezijikelezileyo.

Ukucoceka nokhuseleko:Ukungabikho kwe-chloride ions iqinisekisa ukuthotyelwa kwemigaqo ye-cosmetic (umzekelo, iMigaqo yeCosmetics No. 1223/2009). Iimveliso zokugqibela ziyadibana> 99.5% ukucoceka, kubaluleke kakhulu kwizicelo zolusu.

Ukusebenza kakuhle kwezoqoqosho:Amanyathelo oColi off Action kunye neeNtetho eziPhezulu zeMveliso eziSisiseko zokuLawulwa yi- ~ 30%, zibonelela ngezinto ezikhuthazayo kubavelisi.

Iimpembelelo zeShishini

Olu lunxuwa lufika ngexesha elibalulekileyo. Ngemfuno yehlabathi ye-genoxyethanol eqikelelwe ukukhula kwi-5.2% ye-chagr (2023-2030), iqhutywa ziindlela zendalo kunye ne-orgatic cosmetic zendalo kunye ne-orgactic zendalo, abavelisi bezinto ezichaphazelekayo zijamelana nezenzo zendalo. Iinkampani ezinje nge-basf kunye ne-claric sele zilinge iinkqubo ezifanayo zekati, ukunika ingxelo kuncitshiswa kweenyawo zekhabhoni kunye nentengiso yexesha ngokukhawuleza. Ngapha koko, ukuxhasa kukaMeqiso ukuxhasa ukuveliswa kwemveliso eyakhiwe, ukuvumela amakhonkco obonelelo ngengingqi kunye nokunciphisa ukukhutshwa okunxulumene nezixhobo.

Amathemba exesha elizayo

Uphando oluqhubekayo lwe-biollene ox le-bio ye-oxlene esuswe kwizibonelelo ezihlaziyiweyo (umzekelo, iswekile ye-ethanol) ukuya phambili kwinkqubo. Umdibaniso weqonga lokuncedisa kwi-AI-eqhutywa yi-AI unokuphucula inkangeleko yesivuno sobomi kunye nobomi babo bonke. Inkqubela phambili enjalo i-phenoxyenol synthesis njengemodeli yokwenziwa kweekhemikhali kwicandelo le-cosmetics.

Ukuqukumbela

I-synthesic synthetic ye-phenoxyenol evela e-Ethylene oxide kwaye i-phenol iyayicacisa indlela ubugcisa bobuchwephesha bunokuvumelana njani nokusebenza ngemali kunye nobuphathi bendalo. Ngokujongana nokusikelwa umda kweendlela zeligic, le ndlela ayihlangabezana nje neemfuno zentengiso ye-cosmetics kodwa ikwabeka i-benchmark ye-chemistry ye-chemistry yemveliso ekhethekileyo. Njengoko ukhetho lwabathengi kunye nemigaqo uqhubeka nokubeka phambili uzinzo, ezo nyama ziya kuhlala zibalulekile kwinkqubela phambili kwishishini.

Eli nqaku libalaselisa ukuhlangana kwe-chemistry, ubunjineli, kunye nokugcina uzinzo, ukuhambisa itemplate yolwazezo lwexesha elizayo kwimveliso ye-cosmetic.
