Global - Premier Propylene Glycol: Piny ma timo tic madwong

Kite ma nen ku piny man kemikol

Nen man nguce: Propylene glycol nen calu piny ma rangi ope, maleng, man ma mol. Etiye ku midu ma leng man epe ku nguce, ma weko etiye ber pi tic kama mitire ni bedo ku ngec ma rwinyo.

Solubility: Enyutho kero maber mi rubu, ecopo rubu ku pii, ethanol, ether, acetone, chloroform, man piny mukende mapol. Kite eni miyo etiwu calu piny maber man emulsifier i yore matung tung.

Piny ma pire tek: Ku pek pa 76.09 g/mol, propylene glycol utiye ku pek pa 1.036 g/cm3 i 25°C, ma pek nyanok uloyu pii. Kabedo pare mi lyethu utiye - 59°C, ma weko edong i pii i kind lyethu matung tung. Kabedo mi lyethu ucungo i 188.2°C ithe rwom ma malu, ma nyutho bedo maber i rwom ma malu mi kabedu. Kabedo mi lyethu utiye malo, 99°C (ma cego - kopo), ma jwigo peko mi lyethu.

Reaction pa kemikol: Calu diol, propylene glycol copo timo tic i kit tic matung tung ma nen calu kongo. Ecopu bedu esters ka juporo ku carboxylic acids, ma piretek i yubu piny madwong ma juyubu i tic man piny ma dhanu tiyo kudu. Mi medo, ecopu kadhu kud i timo mi dehydration i thenge moko, ma kelo yik pa intramolecular cyclic ethers nyoke intermolecular polymers.

Tic mi cam man kongo: Propylene glycol timo tic madwong in dul eni. Etimo tic calu humectant, ma konyo ni gwoko pii i cam ma juyubu i mugati, confectioneries, man cak, ma medo kwo migi man gwoko leng pa cam. Calu piny ma jwigo, jutiyo kudu pi jwigo midu, rangi, man piny ma gwoko piny, mi ketho poko piny marom rom i cam man kongo. Ku lapor, nwangire pol kare i jam maku ma leng man calu piny ma tingo moo ma pire tek i cam. Juyio bende ni piny ma ju medo i cam (E1520) i European Union, man juyio ni ber (GRAS) ni US Food and Drug Administration (FDA) ka jutiyo kudu i rwom ma juketho.

Tic mi yath: I lembe mi yath, propylene glycol timo tic ma pire tek. Jutiyo kudu lee calu jamb tiyo ku yath ma nyai ungo i pii, ma konyogi ni bedo yath ma jumadhu, ma jumaku i cing dhanu, man ma jumaku iwi dhanu. Ku lapor, i yath mapol ma pii, propylene glycol konyo ni jwigo piny ma tiyo i yath, ma weko jupoko yath maber. I yath ma jutiyo kudu ikum adila calu cream man ointments, etiyo calu humectant man penetration enhancer, ma medo kero pa adila ni mako yath. Man de etiye ku piny moko ma jwigo kwidi man kwidi, ma konyo ni gwoko piny ma juyubu ku yath.

Piny mi deyo man gwoko kum: Propylene glycol ubedo piny ma pire tek ma jutiyo kudu pi gwoko leng pa kum man piny mi gwoko kum. I piny ma jutiyo kudu pi gwoko adila calu moisturizers, serums, man cleansers, etiyo calu humectant, ma kwanyo pii kud i yamu man mako adila, ma weko adila bedo maleng. Kite ma etiye kudu mi poko piny miyo ecopo poko piny matung tung ma tiyo man nguce, ma weko gi pokore marom rom i piny ma jucul. Jutiyo kudu de i piny mi gwoko yuk wic calu shampoo man conditioner pi medo leng pa yuk wic man konyo i kelo piny maber i yuk wic. I rangi mi lwith, propylene glycol timo tic calu piny ma ketho rangi pa lwith, ma gwoko lwith kud doko ma nyap man nyai nya yot.

Tic mi tic: Propylene glycol ubedo piny ma pire tek iyubu piny matung tung mi tic. Etiye piny ma pire tek ma jutiyo kudu pi yubu unsaturated polyester resins, ma jutiyo kudu lee i yubu fiberglass - plastics ma juyubu. Plastik eni nwango tic i tic macalo mutukari, gedo, man nam, pi tego migi ma malu - ku - pek pa ratio man kero migi mi juku nyai. I tic mi yiku mutukari, propylene glycol - antifreeze man coolant formulations jutiyu kudu pi jwigo lyethu pa cuma, ma jwigo lyethu man ngico. Man de etiwu calu piny ma jwigo man tingo piny i rangi, ink, man adhesives, ma medu tic migi man tic migi.

Yore mi yiko

Epoxy Propane Hydrolysis: Eni ubedo acel ikin yore ma pol pa tic mi yubu piny. I lembe maeni, epoxy propane (propylene oxide) timo tic ku pii i bedo pa catalyst. Adwogi copo timere i thenge matung tung. I yore mi pii - hydration, lyethu ma malu (i kind 150 - 200°C) man kero (0.98 - 2.94 MPa) jutiyu kudu, ku pii - ku - epoxy propane molar ratio ma romo 20. Kadi bende rwom mi loko epoxy propane ni propylene glycol copo tuc i 85% polylene glycol, pollyproly polycolpy moko utiye. de juyubu. Yore mange utiye acid - catalyzed hydrolysis, kama ju medo iye acid catalyst manok (macalu sulfuric acid). Lembe ne timere i lyethu ma piny (50 - 70°C), man piny ma wok kudu mitire ni juyike man juyike maleng nikadhu kud i yore macalo vacuum distillation pi nwangu propylene glycol ma leng.

Glycerol Catalytic Hydrogenolysis: Glycerol copo bedu piny ma jutiyo kudu pi yubu propylene glycol. I yore maeni, glycerol mir acel ukadhu kud i protonation pa hydroxyl groups pare, man ingeye intramolecular dehydration mi yubu piny ma tung tung calu enols man keto - aldehyde tautomers. Piny ma wok ikind piny eni gi kadhu kud i hydrogenation i bedo pa catalyst (macalu copper - based catalyst), ma i ajikine gi nwango 1,2 - propylene glycol. Yore maeni utiye ku bero mi tic ku piny ma juyubu (glycerol), ma jucopu nwangu kud i yore macalo yubu biodiesel.

Yore mi Biotechnology: Piny moko ma nok, calu kit bacteria moko man yeast, jucopo yubu gi ni yubu propylene glycol nikadhu kud i timo fermentation. Ku lapor, ku loko Escherichia coli nyo Klebsiella pneumoniae, jucopo ketho gi loko sukari (macalu glucose) nyo glycerol ni propylene glycol. Yore mi biotechnology eni ber pi kwo pa piny ka juporo ku yore macon mi kemikol, pi en etiyo i piny ma yot man ecopu tiyo ku piny ma nyayu yamo ma nyen. Ento, tic maber man bey pa yore eni podi utiye kabedo mi sayu lembe man mi yubu.

Lembe mi yot kum: Kadi bende propylene glycol juyike ni ber pi tic kudu i cam, yath, man piny mi deyo i rwom ma juyiyu, bedo i iye madwong nyo camu copo bedu ku adwogi marac ikum yot kum. Madhu madwong copo kelo lanyuth macalo ic, ngok, man ic ic. I lembe ma rac, ecopu nyayu metabolic acidosis, two ma kum dhanu bedo ku acid madwong. Ka adila ucungu ku propylene glycol copo nyayu anyonga i dhanu moko, asaga mandha ju ma adila migi nyap. Bedo iwi adila pi kare malac nyo wang mapol ucikere ni juku. Ka jutiyo kudu i kabedo mi tic, yamo maber mitere pi juku yweyo pa propylene glycol vapors, pi yuyu ma lee copo nyayu peko mi yweyo.

Peko mi mac man nyai: Propylene glycol ubedo piny ma wango mac, kadi nya etiye ku rwom ma malo mi wango mac. Yamu pare copo bedu piny ma nyai ku yamu i thenge moko. Kabedo mi kano piny man mi mako piny ucikere ni bedo cen kud mac, lyethu, man piny mukende ma nyayu mac. Jam gwoko piny ma mac copo wango ngo man jam tic maber mi jwigo mac ucikere ni bedu nuti kama propylene glycol jugwoko i iye nyo jutiyo kudu.
Adwogi pa kabedu: Kadi bende propylene glycol copo nyothre, ka juwodho madwong i kabedu, asaga i pii, ecopu bedu ku adwogi. I kind piny ma kwo i pii, ecopu tiyo ku oxygen kani etho, ma copo nyayu peko i kum kwo mi pii.
