Mawu Oyamba

1,6-Hexanedithiol ndi organic pawiri. Ndi madzi achikasu onyezimira opanda utoto okhala ndi dzira lovunda kwambiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 1,6-hexanedithiol:

 

Ubwino:

1,6-Hexanedithiol ndi gulu lomwe lili ndi magulu awiri ogwira ntchito a thiol. Amasungunuka m'madzi ambiri monga ma alcohols, ethers, ketones, koma osasungunuka m'madzi. 1,6-Hexanedithiol ili ndi kukhazikika bwino komanso kutsika kwa nthunzi.

 

Gwiritsani ntchito:

1,6-Hexanedithiol ili ndi ntchito zambiri zomwe zimagwiritsidwa ntchito pamakampani opanga mankhwala ndipo nthawi zambiri zimagwiritsidwa ntchito ngati reagent mu organic synthesis. Itha kugwiritsidwa ntchito pokonzekera mankhwala okhala ndi zomangira za disulfide, monga disulfides, thiol esters, ndi disulfides, pakati pa ena. 1,6-Hexanedithiol itha kugwiritsidwanso ntchito ngati chowonjezera chothandizira, antioxidants, retardants lamoto ndi othandizira zitsulo pamwamba.

 

Njira:

Njira yodziwika bwino yophatikizira ndikupeza 1,6-hexanedithiol pochita hexanediol ndi hydrogen sulfide pansi pamikhalidwe yamchere. Mwachindunji, yankho la lye (monga sodium hydroxide solution) limayamba kuwonjezeredwa ku organic solvent kusungunuka mu hexanediol, ndiyeno mpweya wa hydrogen sulfide umawonjezeredwa, ndipo pakapita nthawi, chinthu cha 1,6-hexanedithiol chimapezeka.

 

Zambiri Zachitetezo:

1,6-Hexanedithiol ndi fungo lonunkhira bwino lomwe lingayambitse mkwiyo komanso kusasangalatsa likalowa m'maso kapena pakhungu. Kukhudza khungu ndi maso kuyenera kupewedwa mukamagwiritsa ntchito komanso kuvala zida zoyenera zodzitetezera. 1,6-Hexanedithiol ndi madzi oyaka, ndipo njira zotetezera moto ndi kuphulika ziyenera kuwonedwa. Mukamasunga ndi kusamalira, ndikofunikira kutsatira njira zoyendetsera chitetezo ndikuwonetsetsa kuti mpweya wabwino umakhala wabwino.
