Vagadziri zvakanaka mutengo wakaburitsa acid Cas: 57-11-4 fanika mufananidzo

Tsananguro pfupi:

Stearic Acid: (Maindasitiri Giredhi) Octidecanoc acid, c18h36o2, inogadzirwa neHydrolysis yemafuta uye inonyanya kushandiswa mukugadzirwa kweStearate
Stearic Acid-829 Stearic Acid, Stearic Acid Fatty yakawanikwa kubva kumhuka uye miriwo inoba (c18h36o2) uye palmiti acid (c16h32o2).
Ichi chigadzirwa chakachena kana chena senge poda kana crystalline yakaoma block, profil yayo ine microstrip inosimbisa tsono yakanaka; Iyo ine shuwa kushoma yakafanana neye mafuta uye haina kurwara. Ichi chigadzirwa chinonyura mu chloroform kana diethyl ether, yakanyungudika mu ethanol, ingapenge kuine mvura. Freezing point the freezing point (Appendix ⅵ d) yechigadzirwa hachifanirwe kuderera pane 54 ℃. Idiine kukosha kweIODINE kukosha kwechigadzirwa ichi (Appendix ⅶ h) isingadivi 4. (White Likecipitate)

Zvikumbiro zveAcric acid

Stearic acid, (maindasitiri giredhi) Stearic acid ndeimwe yeakakura marefu-keteni mafuta acids inosanganisira mafuta nemafuta. Izvo zvinoratidzwa mumafuta emhuka, mafuta uye mamwe marudzi emafuta emiriwo seanoporesa chimiro cheglycerides. Mafuta aya, mushure mehydrolysis, gadzira iyo yakadzika acid.
Stearic Acid ndeye Fatty Acid zvakanyanya iripo mune zvakasikwa uye ine general makemikari zvivakwa zve carboxylic acids. Anenge marudzi ese emafuta nemafuta ane imwe huwandu hwesidic acid nezviri mumhuka dzinopera. Semuenzaniso, zvirimo mubhota zvinogona kusvika kusvika ku25% zvichiratidzika mumiriwo iwo mafuta ane hukama akaderera neyekukosha mune tii yemafuta kuva 0.8% uye nemafuta muchanza kuve muchindwe kuve 6%. Nekudaro, zvirimo muCocoa zvinogona kusvika kumusoro kunge 34%.

Pane nzira mbiri huru dzekugadzira maindasitiri ekunyanyisa acid, enderedzwa-fraction uye nzira yekumanikidza. Wedzera OCCOMPOTION OICTER kune iyo Hydrogenated Oiri, uyezve Hydrolyze kupa iyo isina kujairika mafuta acid, kuenderera mberi nekushambidza nemvura, kushora, kusviba kuti uwane zvigadzirwa zvapera nejlyceroct.
Vazhinji vagadziri vepamba vanoshandisa mafuta emhuka yekugadzira. Mamwe marudzi ekugadzira tekinoroji anozoguma nekureba kwekusakwana kweiyo distillation yeakakora iyo acid iyo inoburitsa kunhuhwirira panguva yekugadzirisa kwepurasitiki uye kupisa kwakanyanya. Kunyangwe izvi zvinonhuwira hazvisi zvepfuu asi ivo vachave nemhedzisiro yemamiriro ekushanda uye nharaunda yakasikwa. Yakanyanya kuendesa fomu yekutsvaira acid inotora mafuta emiriwo seyakaomeswa, maitiro ekugadzira anowedzeredzwa; Iyo yakaburitswa yakakwenenzverwa acid ndeye yakagadzikana performance, yakanaka yekuisa midziyo uye kushoma kunhuhwirira mukushandisa.
Stearic Acid inonyanya kushandiswa kugadzirwa kweiyo sodium steatate, magnesium stearate, tungamira Stearate, aluminium Stearate, Simbi Stearate, Iron Stearate, uye potassium Stearate. Iyo sodium kana potassium munyu weStearic Acid ndiyo chikamu che sipo. Kunyangwe sodium stearate ine kugona kushomeka kupfuura sodium pregmitate, asi kuvapo kwayo kunogona kuwedzera kuomarara kwesipo.
Tora butter seyakaisa zvinhu, enda neslfuric acid kana yakamanikidzwa nzira yekuenda kuDocucsition. Iyo yemahara yemahara acids yaive yekutanga pasi pemvura yekumanikidza yekubvisa iyo Palmiti acid uye olic acid paEthanol, ichimutswa neyeganium accetate kana magnesium acetate iyo inoenderana neyekuenderana neyekuenderana neyekufamba-famba. Wobva wawedzera kuwedzera Dilute Sulfutic Acid kuti uwane iyo yemahara Steat
