Cov Txheej Txheem Propionic Acid Acetylene
1. Kev Npaj Khoom Siv Raw Propionic Acid
Cov khoom siv raw rau cov txheej txheem acetylene suav nrog acetylene, oxygen, thiab dej. Acetylene tau los ntawm cov chaw ua roj lossis cov chaw tsim tshuaj, thaum oxygen tau los ntawm cov chaw sib cais cua.
2. Cov txheej txheem tshuaj tiv thaiv
Kev Kho Mob Ua Ntej: Acetylene thiab oxygen raug kho ua ntej sib cais rau qhov kub thiab txias kom ntseeg tau tias cov tshuaj tiv thaiv ua haujlwm tau zoo.
Cov tshuaj tiv thaiv carbonylation: Cov acetylene thiab oxygen uas tau kho ua ntej lawm raug sib xyaw thiab raug rau cov tshuaj tiv thaiv carbonylation nyob rau hauv qhov muaj cov tshuaj catalyst. Cov kauj ruam no tshwm sim nyob rau hauv qhov kub thiab txias siab thiab siab, feem ntau ntawm 180–200 ° C thiab 0.8–1.2 MPa.

Propionic Acid - Shandong Pulisi Chemical Co., Ltd.         info@pulisichem.cn
Shandong Pulisi Chemical Co., Ltd. yog ib lub tuam txhab tsim khoom thiab muag khoom ntawm propionic acid (CAS 79-09-4) hauv Suav teb, muab cov khoom zoo nrog cov saw hlau ruaj khov thiab cov txheej txheem tswj xyuas zoo. Peb cov propionic acid, tseem hu ua propanoic acid, yog cov roj fatty acid luv luv nrog cov mis molecular CH₃CH₂COOH thiab qhov hnyav molecular ntawm 74.08. Nws zoo li cov kua tsis muaj xim, ntshiab, thiab corrosive nrog cov ntxhiab tsw pungent, thiab sib xyaw nrog dej, ethanol, ether, thiab lwm yam organic solvents.
Peb tsim cov propionic acid los ntawm cov txheej txheem tsim khoom lag luam siab heev, kom ntseeg tau tias muaj kev ntshiab siab thiab kev ua tau zoo sib xws rau ntau yam kev siv hauv kev lag luam. Ua ib qho tseem ceeb ntawm cov tshuaj lom neeg nruab nrab, peb cov propionic acid siv dav hauv ntau qhov chaw: hauv kev lag luam khoom noj thiab pub tsiaj, nws ua haujlwm ua cov khoom siv tiv thaiv thiab tiv thaiv pwm rau cov nplej, cov khoom ci, thiab cov tsiaj txhu, thaum tseem ua haujlwm ua cov khoom siv raw rau kev tsim sodium propionate thiab calcium propionate; hauv kev lag luam tshuaj lom neeg, nws ua haujlwm ua tus neeg sawv cev esterification, cov kuab tshuaj rau nitrocellulose, plasticizer, thiab ib qho tseem ceeb rau kev tsim cov tshuaj tua kab, fungicides, thiab cov tshuaj tsw qab; ntxiv rau, nws pom cov ntawv thov hauv cov tshuaj electroplating, kev tsim tshuaj, thiab ua tus neeg tiv thaiv viscosity hauv kev tsim npias.
Ntawm Shandong Pulisi Chemical, peb muab qhov tseem ceeb rau cov khoom zoo thiab kev txaus siab ntawm cov neeg siv khoom. Peb cov propionic acid tau ntim rau hauv cov nruas txheem lossis ISO tanks kom ua tau raws li cov kev xav tau sib txawv ntawm kev xa khoom thiab kev khaws cia, nrog rau cov lus qhia kev nyab xeeb rau kev tuav, kev thauj mus los, thiab kev khaws cia. Peb muab ob qho tib si ntau thiab cov kev pabcuam xaj tshwj xeeb, ua kom tau raws li cov kev xav tau tshwj xeeb ntawm cov neeg siv khoom thoob ntiaj teb los ntawm ntau thaj chaw. Nrog ntau xyoo ntawm kev paub txog kev tsim tshuaj lom neeg thiab kev lag luam txawv teb chaws, peb cog lus tias yuav muab cov khoom lag luam propionic acid zoo, cov nqi sib tw, thiab kev txhawb nqa tom qab muag zoo los tsim kev sib raug zoo ntev nrog cov neeg koom tes thoob ntiaj teb.
