Morphology thiab cov khoom yooj yim ntawm diethylhydroxylamine

Daim ntawv ntshiab: tsis muaj xim thiab pob tshab kua.
Daim ntawv khoom lag luam: kua daj daj ntshiab.
Kev Ruaj Ntseg: Ruaj khov ntawm chav tsev kub, tab sis khaws cia ntev lossis raug tshav ntuj ncaj qha lossis raug cua yuav ua rau xim maj mam hloov daj.
Kev yaj: Yooj yim yaj hauv dej, cov kua dej yog qaug zog alkaline rau daim ntawv litmus, thiab yaj hauv ethanol, ether, chloroform, benzene thiab lwm cov kuab tshuaj organic.
Lwm yam khoom: Nws yuav ua rau nws muaj huab ib ntus tom qab co hnyav thiab yuav ploj mus tom qab ob peb teev; muaj ntxhiab tsw ntawm amine; nws yooj yim hlawv thiab tsim cov pa nitrogen oxides lom, thiab cov pa thiab cua tuaj yeem tsim cov khoom sib xyaw ua ke; nws lom thiab ua rau lub qhov muag thiab daim tawv nqaij khaus.

Diethylhydroxylamine (DEHA luv luv) yog ib qho organic compound nrog cov tshuaj formula C4H11NO thiab qhov hnyav molecular ntawm 89.14. Nws yog ib qho nruab nrab-lub zog organic reducing agent thiab siv dav hauv kev tsim tshuaj lom neeg, xws li polymerization inhibitors thiab antioxidants, agents, stabilizers, thiab lwm yam.

Thov nco ntsoov tias vim yog qhov tshuaj lom thiab kev kub hnyiab ntawm diethylhydroxylamine, cov cai tswjfwm tsim nyog yuav tsum tau ua raws li nruj me ntsis thaum siv thiab khaws cia kom ntseeg tau tias muaj kev nyab xeeb.

Kev siv cov tshuaj diethylhydroxylamine

Kev Tsim Tshuaj: Ua tus neeg sawv cev txo qis nruab nrab, diethylhydroxylamine siv dav hauv kev tsim tshuaj thiab tuaj yeem siv ua tus neeg tiv thaiv polymerization, antioxidant, stabilizer, thiab lwm yam.

Cov tshuaj tiv thaiv polymerization: Siv rau hauv kev tsim khoom thiab khaws cia cov conjugated olefins xws li styrene thiab divinylbenzene kom tiv thaiv kev polymerization tsis tau xav txog.
Cov tshuaj antioxidants: siv rau olefin monomers, polyolefins thiab lwm yam organic compounds kom ntev lub sijhawm khaws cia.
Terminator: Nres lossis qeeb qeeb qhov kev ua polymerization kom tswj tau cov khoom ntawm polymer.

Lwm cov ntawv thov kev lag luam:

Kev Lag Luam Tshuaj Tua Kab: Ua ib yam khoom siv raw rau tshuaj tua kab, fungicides, thiab herbicides.
Kev Lag Luam Xim: Ua ib qho tseem ceeb nruab nrab, nws koom nrog hauv kev tsim cov xim sib txawv.
Roj hmab teb: Txhim kho kev laus tiv taus thiab kev cuam tshuam ntawm cov khoom roj hmab.
Lub Zog Tshiab: Siv ua cov khoom siv npaj rau cov vaj huam sib luag hnub ci, muab cov khoom siv photoelectric zoo heev.
Kev lag luam tshuaj: cov khoom siv tseem ceeb rau kev tsim cov tshuaj.
Diethylhydroxylamine ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw, thiab nws txoj kev txhim kho daim ntawv thov tseem tab tom ua.
