| 1,5-Pentanediol Siv Thiab Synthesis |
| Chemical Properties | 1,5-Pentanediol (PDO) yog cov tsis muaj xim, oily kua nrog cov yam ntxwv tsw. Nws yog miscible hauv dej thiab cov kuab tshuaj organic. Nws tau txais tom qab kev kho mob ntawm kev sib tov ntawm cov khoom uas tshwm sim los ntawm oxidation ntawm cyclohexane nrog huab cua. PDO yog lub tsev thaiv rau saturated polyesters, unsaturated polyesters thiab polyurethanes, hnyav rau inkjet number case formulations. Nws yog qhov tsim nyog rau polyesters rau cov xim hnyav hnyav (stoving enamels, ob lub ntsiab lus xim, tuaj yeem & coil txheej), polyester plasticizers thiab rau cov ntu muag rau polyurethanes. |
| Siv | 1,5-Pentanediol muaj ntau yam kev siv. Intermediate pom cov ntawv thov hauv Cov Khoom Siv Taw Qhia rau cov tshuaj syntheses, Inks thiab coatings, Plasticizers thiab Solvent, Industrial chemicals. 1,5-Pentanediol yog siv los ua plasticizer hauv cellulose cov khoom thiab cov nplaum. Nws yog siv los ua ib tug brake kua additive. Nws reacts nrog 3,4-dihydro-2H-pyran kom tau 5-tetrahydropyran-2-yloxy-pentan-1-ol. Nws kuj yog siv los npaj polyesters rau emulsifying tus neeg sawv cev thiab resin intermediates. nws yog siv nyob rau hauv ink, toner thiab colorant khoom. Nyob rau hauv tas li ntawd, nws yog siv nyob rau hauv lub brake kua compositions. 1,5-Pentanediol yog siv los tsim cov ntaub ntawv ua los ntawm polyester lossis polyurethane, rau kev tsim cov monomers, rau kev tsim cov polyester polyols, polycarbonatedioles thiab acrylic monomers, rau zus tau tej cov delta valerolactone thiab molecules uas ua raws li reactive. diluents, rau zus tau tej cov halogenated tshuaj thiab rau zus tau tej cov adhesives, putties thiab sealing tebchaw, ntxuav thiab auxiliary agents. siv nyob rau hauv cov txheej txheem los tsim hydrogen, hydrogen peroxide, sodium perborate thiab peroxyacetic acid thiab ua ib qho nruab nrab rau cov khoom siv tshuaj. Nws yog siv los ua cov khoom siv rau kev tsim cov polymeric thickeners, plasticizers rau polyvinyl chloride, sizing agents, surfactants, starches thiab chemically modified starch rau daim ntawv, textile thiab zaub mov kev lag luam, rau tus kheej tu cov khoom xws li tshuaj zawv plaub hau, cream, thiab rau xim. |
| Health Hazard | 1,5-Pentanediol tsis muaj cov cim kev phom sij rau kev noj qab haus huv. Nws qhov mob toxicity tsawg heev ntawm txhua txoj kev raug kuaj (qhov ncauj, tawv nqaij thiab nqus tau pa). Nws tsis muaj kev cuam tshuam los yog ua rau muaj kev puas tsuaj. Kev txhaj tshuaj tsawg dua thiab kev noj qab haus huv mus sij hawm ntev lossis kev ua me nyuam muaj txiaj ntsig tau tsim nrog nws tus kheej. Cov ntaub ntawv nthuav dav ntxiv yog muaj rau cov tshuaj sib piv 1,5-Hexanediol. Raws li tag nrho cov ntaub ntawv muaj Nws tsis xav tias yuav ua rau muaj kev noj qab haus huv ntau dua lossis ntev dua. Lub cev muaj zog ntawm 1,5-Pentanediol tsis muaj kev txhawj xeeb. Nws flammability yog tsawg. Yog li ntawd, Nws muaj peev xwm ua rau tib neeg noj qab haus huv tsawg heev. |
