Zvinhu zvakawanda zvemakemikari zvinovanda muzvigadzirwa zvakasiyana-siyana muhupenyu hwezuva nezuva, zvichitsigira kugadzirwa kwemaindasitiri uye kuvandudza hupenyu hwevanhu, uye methyl propanol inomiririra zvakanyanya pakati pavo. Vanhu vazhinji havazivi zita iri remakemikari, asi rinogona kuwanikwa mumachira emukati, manamati, zvigadzirwa zvekuchengetedza ganda zvezuva nezuva uye mapurasitiki emaindasitiri. Semusanganiswa weorganic une hunhu hwakanaka, methyl propanol yave chinhu chakakosha muindasitiri yemakemikari, zvinhu uye makemikari ezuva nezuva, ichishanda se "bhiza rebasa risingaonekwe remaindasitiri".
Methyl propanol, inonzi nesainzi 2-methyl-1,3-propanediol (MPO) ine molecular formula C₄H₁₀O₂, idiol chaiyo. Inotaridzika semvura isina ruvara, yakajeka uye ine viscosity shoma ine magadzirirwo akachena, kuyerera kwakanaka uye hunhu husina hwema hwakanyanya, izvo zvinoisa hwaro hwekushandiswa kwayo kwakasiyana-siyana muminda yakasiyana-siyana. Panyaya yehunhu hwayo, inoita basa rakanaka: ine poindi yekunyunguduka yakaderera ye -91°C uye poindi yekufashaira ye 213°C, zvichiita kuti ikwanise kutsungirira tembiricha yakakura ine resistance yakanaka yekupisa kwakaderera uye kugadzikana kwekupisa. Panguva iyi, ine insolvent inoshamisa, inosanganiswa zvizere ne solvents dzakajairika dzakadai semvura, ethanol ne acetone, ukuwo isinganyungudike mune solvents dzisiri dzepolar dzinosanganisira benzene ne cyclohexane, zvichiita kuti ive yakakodzera kugadzirwa kwemaitiro akasiyana-siyana e formula.
Kana ichienzaniswa nealcohols dzakajairika, methyl propanol ine mabhenefiti akanyanya kukosha ehunhu hwakachengeteka uye hwakasimba hwemakemikari. Haiwanzo kuora kana kuora patembiricha yemumba, isina kuora, kusagadzikana kwakaderera uye kutsva kwakaderera. Flash point yayo inenge 100°C, ichitevedzera mitemo yekuchengetedza maindasitiri. Panyaya yemamorekuru, mapoka ayo maviri makuru ehydroxyl uye mapoka emethyl epadivi anoipa reactivity inochinjika. Inogona kutora chikamu mukuita kwakasiyana-siyana kwemakemikari senge esterification uye acetalization kugadzira zvinhu zvakasiyana-siyana zvepolymer. Maitiro ekuita reaction akapfava uye anogona kudzorwa pasina kugadzira zvinhu zvakawanda zvinokuvadza, zvichienzanisa kushanda uye hushamwari hwezvakatipoteredza - iyi ndiyo mukana wayo mukuru pane zvinhu zvakafanana zvemakemikari.
Ichibatsirwa nehunhu hwayo hwepamusoro hwemuviri nemakemikari, methyl propanol inofukidza nzira dzakasiyana-siyana dzekushandisa mukugadzirwa kwemaindasitiri uye zvigadzirwa zvehurumende. Muindasitiri yezvinhu zvepolymer, chinhu chakakosha pakugadzira polyester nepolyurethane. Kana ikashandiswa mukugadzirwa kwezvinhu, inogona kuvandudza kuchinjika, kuramba mamiriro ekunze uye kuramba kupisa kwezvigadzirwa, kuderedza viscosity yezvinhu, uye kuita kuti machira apedzwa nemaresini ave akapfava uye agare kwenguva refu. Inoshandiswa zvakanyanya mukugadzira nekugadzira machira eindasitiri, mapurasitiki einjiniya uye elastomers. Pamusoro pezvo, inogona kushandiswa kugadzira zvinowedzera zvepurasitiki zvakaita semapurasitiki uye maantioxidants, kuwedzera hupenyu hwebasa uye kugadzirisa magadzirirwo ezvigadzirwa zvepurasitiki.
Mumaindasitiri emakemikari akanaka uye emakemikari ezuva nezuva, methyl propanol inoshanda semushonga wepamusoro-soro unochengetedza nharaunda uye unobvisa ganda kubva muganda. Nekuda kwehunhu hwayo husina chepfu uye hunonyungudutsa mumvura, inowanzo wedzerwa muzvigadzirwa zvekuchengetedza ganda uye zvekushongedza kuti inyorovese ganda, kugadzirisa mafomula uye kunatsiridza kunzwa kweganda pasina kukonzera kushatirwa kweganda. Uyezve, inoshanda pakugadzira fomura yeinki, manamatisi uye zvinhu zvekuchenesa, izvo zvinogona kuwedzera kunamira uye kufanana kwezvigadzirwa, kuderedza kusagadzikana kwezvinhu zvinokuvadza, kuvandudza mwero wekudzivirira nharaunda wezvigadzirwa zvakapedzwa, uye kugadzirisa mamiriro akasiyana-siyana akadai sekushongedza dzimba, zvinyorwa zvekushandisa uye kugadzira indasitiri yechiedza.
Kunyangwe methyl propanol iri kemikari ine njodzi shoma uye inoshanda zvakanyanya kuchengetedzeka, zvinodiwa kuti ishandiswe uye ichengetwe zuva nezuva. Zvigadzirwa zvakapedzwa zvine methyl propanol zvakachengeteka kuti zvisanganiswe nevanhu pasina kunetseka zvakanyanya. Methyl propanol yakachena inofanira kuchengetwa munzvimbo inotonhorera uye ine mhepo, kure nekupisa kwakanyanya uye moto wakashama, uye yakaparadzaniswa ne oxidants dzakasimba. Mumabasa emaindasitiri, matanho ekudzivirira akajairika anofanira kutorwa kudzivirira kusangana kwenguva refu uye kumedzwa netsaona. Maitiro ekutanga ekushandisa makemikari anogona kudzivirira njodzi dzinogona kuitika.
Nekupararira kwepfungwa yemakemikari egirini, zvinhu zvemakemikari zvisina chepfu yakawanda, zvakagadzikana uye zvinoshanda zvave chinhu chikuru mukukura kwemaindasitiri. Zviine tekinoroji yekugadzira yakakura, kushanda kwakasimba, hushamwari kune zvakatipoteredza uye kuchengetedzeka, methyl propanol yakatsiva zvishoma nezvishoma mamwe maalcohols echinyakare ane kusvibiswa kwakanyanya uye ane njodzi huru, uye kushandiswa kwayo pamusika kuri kuramba kuchiwedzera. Kukosha kwayo kuri kuongororwa nguva dzose mukugadzira maindasitiri echinyakare, indasitiri yemakemikari epamusoro-soro uye indasitiri yemakemikari egirini ezuva nezuva.
Mukupedzisa, kunyangwe zvichiita sezvisina basa, methyl propanol chinhu chakakosha asi chisingatariswe mumaindasitiri emazuva ano. Nekushanda kwakagadzikana uye kugona kuchinjika kwakakura, inopinda mukona yega yega yehupenyu hwedu, ichivandudza chinyararire mhando yechigadzirwa uye mararamiro evanhu. Kunzwisisa methyl propanol hakusi kungoziva chete chinhu chemakemikari, asiwo kuona runako rwakasiyana rwemakemikari emazuva ano akanaka anoshanda uye anobatanidzwa muhupenyu hwezuva nezuva.
