| Hazard Cov Cim | Xi-xaj |
Taw qhia
Acid yog cov khoom siv organic nrog cov tshuaj formula C6H5O3S, uas yog tsim los ntawm kev sib txuas ntawm pawg carboxylic acid thiab ib pawg hydroxyl ntawm 2nd txoj hauj lwm ntawm lub nplhaib thiophene. Hauv qab no yog cov lus piav qhia ntawm qhov xwm txheej, kev siv, kev npaj thiab kev nyab xeeb cov ntaub ntawv ntawm polymer acid:
Xwm:
-Zoo: acid yog dawb mus rau lub teeb daj.
-Solubility: Nws tuaj yeem yaj hauv dej thiab qee cov kuab tshuaj organic (xws li cawv thiab ketones).
- Melting point: Nws melting point yog hais txog 235-239 ° C.
Siv:
-Chemical synthesis: acid tuaj yeem siv los ua ib qho nruab nrab rau kev sib txuas ntawm lwm cov organic tebchaw, xws li kev npaj ntawm thiophene compounds, dyes thiab tshuaj intermediates.
- Cov ntaub ntawv tshawb fawb: Polymers synthesized los ntawm cov kua qaub tuaj yeem siv los npaj cov organic nyias-film solar cells thiab organic field-effect transistors thiab lwm yam khoom siv.
Txoj Kev Npaj:
Muaj ntau txoj hauv kev los npaj calcium acid. Ib txoj kev siv feem ntau yog ua rau 3-hydroxythiophene nrog cov kua qaub hydrogen uas tsim nyog (xws li cov kua qaub chloride compound).
Cov ntaub ntawv kev nyab xeeb:
-tsis muaj kua qaub tsis muaj qhov pom tseeb muaj tshuaj lom thiab cov kev mob tshwm sim qhia nyob rau hauv ib txwm siv.
-Vim hais tias txhua tus neeg qhov rhiab heev rau cov tshuaj sib txawv, kev siv yuav tsum ua raws li cov txheej txheem kev nyab xeeb, xws li hnav cov hnab looj tes tiv thaiv, tsom iav thiab cov khaub ncaws kuaj, kom tsis txhob sib cuag nrog daim tawv nqaij lossis hauv qhov muag.
-Thaum khaws cia, khaws cov kua qaub rau hauv qhov chaw qhuav thiab qhov cua zoo, kom deb ntawm qhov chaw sov thiab cov khoom siv hluav taws xob.
Thov nco ntsoov tias cov ntaub ntawv saum toj no tsuas yog siv rau kev siv xwb. Thov ceev faj thaum siv los yog tuav cov kua qaub, thiab xa mus rau cov ntaub ntawv tshuaj lom neeg ntseeg tau kom paub meej ntxiv thiab raug.
