Taksa le Chemical sining

A muisam le a sining: Adipic Acid cu a tlangpi in a rangmi, a senmi buh asiloah a hmete, rong a ngei lomi lungvar bantuk in a lang. A nemmi a ngei i a ttha mi thil sining ah rim a ngei lo, cu nih cun a tlarimi hngalh khawhnak sining a herhnak hmun ah hmannak phunphun caah aa tlakter.
A cawh khawhnak: Ti chungah a tlawmpal a cawh khawhnak a langhter, 25°C ah ti 100 mL ah 1.44 g hrawng a cawh khawh. Sihmanhsehlaw, ethanol, acetone le benzene tibantuk thilnung hna ah a cawh kho ngai. Hi a cawh khawhnak ziaza nih hin chemical thlennak le sernak phunphun ah ttha tein i tel khawhnak a pek.

A biapimi taksa aa thleng lomi: Adipic Acid cu molar mass 146.14 g/mol a si. A ritnak cu 25°C ah 1.36 g/cm3 hrawng a si, cucu ti nakin tlawmpal a rit deuh. Adipic acid a linnak hmun cu 152°C a si, cu nih cun a sangmi lumnak tangah a fekmi in ti bantuk dirhmun ah aa thlennak a langhter. A linnak hmun cu 337.5°C ah a cang, asinain thli hneknak tangah hi lumnak a phak hlanah a rawk hram aa thawk men lai. A kanghnak hmun cu 207°C a si, cu nih cun mei kanghnak ttihnung a chuahter khawhnak ding caah a sang deuhmi lumnak le mei kanghnak hrampi a herh ti a langhter.

Chemical Reactivity: Dicarboxylic acid pakhat a si bantukin, adipic acid nih carboxyl riantuannak phu (-COOH) pahnih a ngei, cu nih cun chemical reactivity sang a pek. Zu he esterification thlennak ah fawi tein aa tel, plastic, hriak le rimhmui sernak ah tam deuh hmanmi ester a ser. Cun, diamine he aa pehtlaih khawh i polyamides a ser khawh, a bik in nylon 6,6. Hi polymerization reaction hi synthetic fiber le engineering plastics industry hna i a hrampi a si. Adipic acid zong nih aa tlakmi zu ser awkah tlawmternak lehrulhnak a tuah khawh i adipates tiah theihmi chiti ser awkah bases he aa pehtlaih khawh.

Hmannak Hmun

Polyamide (Nylon) chuahmi: Adipic acid hmannak nganbik le a biapi bikmi cu polyamides sernak ah a um, a bik in nylon 6,6. Hi thil kalning ah hin, adipic acid nih hexamethylenediamine he condensation polymerization reaction ah aa pehtlaih. A chuakmi nylon 6,6 cu a tthawngmi engineering plastic a si i a thazaang, a fekmi, a rawk kho lomi le a ttha tukmi seh thilri hna ruangah minthang a si. Nylon 6,6 cu mawtaw sernak ah engine thilri, gear le bearings tibantuk thilri caah tampi hman a si. Thilpuan sernak ah a biapi tukmi thilri zong a si, cuka ahcun a thazaang, a tuar khawhnak le rong ttha tein a tlaih khawhnak ruangah thilthuam, hnipuan, le thilthuam caah a ttha ngaimi thilpuan sernak ah hman a si.

Plasticizers le Lubricants: Adipic acid cu adipate - based plasticizers sernak caah hman a si. Hi plasticizers pawl hi polymers ah an cawh hna, a bik in polyvinyl chloride (PVC), an nemnak, an hman khawhnak le an fek khawhnak ding caah. Adipate plasticizers cu lumnak tlawmte ah thlen khawhnak a herhmi hmannak ah an duh deuh, cu hna cu mawtaw hri khamnak, sii lei hri, le khuasik a tuar khomi PVC thilri sernak ah an si. Cun, adipic acid in chuahmi ester pawl cu riantuannak phunphun ah hriak ah hman an si, a ttha tukmi rawhralnak le hnahnawhnak dohnak thilri an pek, cun engine, gear le a dang seh thilri hna ah hman awk ah an ttha.

Rawl le dinmi chawlehnak (Indirect hmannak): Adipic acid cu rawl ah direct in hman a si lo nain, rawl - pehtlaihnak thilri le rawl sernak thilri sernak ah hman a si. A ester pawl cu rawl - thilri chiahnak caah khuhnak le kharnak ah hman tikah, rawl thilri hna i an himnak le an himnak kha a thurhnawmhnak kha a kham i thilri thar a siter. Cun, adipic acid - hrambunhmi polymers cu thilri sernak ah hman khawh a si i, rawl sernak ah rawl he aa tongmi thilri pawl, cu hna cu thilri phorhnak hri le kharnak tibantuk an si.

Sii le thilthuam sernak riantuannak: Sii sernak ah, adipic acid cu sii sernak ah bawmtu ah hman khawh a si. Sii sernak cawhnuk le hnahnawhnak pH uk khawhnak caah buffering agent bantuk in rian a ttuan khawh, sii hna i an fekmi le an tthatnak kha a hngalhter. Thilri dawhnak lei ah, adipic acid esters cu thilri phunphun ah hman a si, cu hna cu cream, lotion, le lipstick hna an si, cu nih cun a muisam a tthatter, a karh khawhnak a tthanchoter, cun a nemtertu thil a pek, cu nih cun vun kha a nemter i a nemmi a siter.

Timhtuahnak Lam

Cyclohexane oxidation: Mah cu adipic acid chuahnak caah a lar ngaimi riantuannak lam a si. Mah thil kalning cu cyclohexane a chuahtertu thilri, a tlangpi in cobalt hrambunhmi thilri a um lio ah oxidation tuahnak in aa thawk. A hmasa bik - tthanchonak oxidation ah, cyclohexane nih thli asiloah oxygen he aa pehtlaih i cyclohexanol le cyclohexanone cawhmi a ser, mah thil kalning cu "KA chiti" (ketone - zu chiti) thil kalning tiah theih a si. Cu thil cangmi cu 150 - 160°C hrawng lumnak le 1 - 1.5 MPa tluk a ritmi ah tuah a si. Cu hnu ah, KA chiti cu a pahnihnak - tthanchonak ah nitric acid kha oxidizing agent ah hmangin oxidize a si, a tlangpi in 60 - 80°C lumnak le thli hneknak ah. Hi a pahnihnak - tthanchonak nih cyclohexanol le cyclohexanone cu adipic acid ah a thlen. Sihmanhsehlaw, hi lam nih hin pawngkam kongah harnak cheukhat a ngei, zeicahtiah nitric acid hmannak nih nitrous oxide (N2O) a chuahter, cucu a tthawngmi greenhouse gas a si, cun thilri rawhralnak hna kha ralring tein zohkhenh a herh.

Biotechnological Lamthluan: Nai kum hna ah, a hmunmi lam dang pakhat in adipic acid chuah khawhnak ding caah biotechnological lam hna ah lungthawhnak a karh. Thil hme tete, cu hna cu thlennawnnak in sermi bacteria asiloah thilnu tibantuk hna cu, a tharchuah khawhmi rawl, cu bantuk cu thlum asiloah thingram in sermi chiti hna kha, thilri thlennak lam phunphun in adipic acid ah thlennak caah hman khawh an si. Tahchunhnak ah, bacteria cheukhat cu adipic acid ah thlen khawhmi a karlak thilri chuah khawhnak ding caah ser khawh an si. Hi biotechnological lam hna hi tthanchonak dirhmun ah an um rih i thilchuah khawhnak le man - tthatnak he aa pehtlaimi harnak an ton lio ah, hmailei ah pawngkam he aa remmi le a hmunmi adipic acid chuah khawhnak lam an pek.

Ralrinnak

Ngandamnak caah tihnung: Adipic acid nih direct in tawngh tikah vun le mit a fahter khawh. Caan sau asiloah voi tampi vun i tongh ahcun vun zawtnak a chuak kho, cun mit he aa tongh ahcun a sen, a fah, cun mitthli a hrawh khawh. Adipic acid leidip tlawmpal thawchuahnak nih thawchuahnak lam a hnorsuan khawh, khuh, thawchuah harnak le thawchuah harnak a chuahter khawh. Adipic acid tam tuk ei ahcun pawpi fahnak a chuahter khawh, cu chungah cun luakchuah, luakchuah le zunthlum tibantuk hna an i tel. Adipic acid a hmangmi riantuantu hna nih aa tlakmi pumpak kilvennak thilri, kutdonghrolh, himnak mithmaihuh, le thawchuahnak hmaikhuh tibantuk an i hruk awk a si, a hlei in leidip a chuah khawhnak hmun ah.

Meikanghnak le Puahkehnak Tihnung: Adipic acid cu a linnak hmun a sang ngai ko nain, a kang kho. Powder bantuk in, a za tawk in aa ṭhek ahcun thli he a puak khomi cawhmi a ser khawh. Chiahnak hmun pawl cu mei a chuahnak hmun in hlat tein chiah ding a si, cun leidip a khon lonak ding caah thli luhchuahnak ttha a herh. Adipic acid aa telmi meikanghnak a um ahcun, aa tlakmi meikanghnak thilri, a ro cangmi chemical powder asiloah carbon dioxide tibantuk kha hman ding a si.

Pawngkam hnahnawhnak: Adipic acid cu pawngkam ah a tlawmpal in a hmun. Ti chung ah a chuah tikah, caan saupi chung thilnung hme tete nih an hrawh khawh, asinain a tam tuk ahcun ti chung thilnung cungah hnahnawhnak a pek khawh rih hna. A almi a si caah ti system pH zong a hnorsuan khawh. Cucaah, pawngkam ah adipic acid uk khawh lomi chuah lonak ding caah thilri hnawm zohkhenhnak le khamnak phunglam hna cu a biapi tukmi an si. Adipic acid a chuahtu asiloah a hmangmi riantuannak hna nih vawlei, ti le thli tthatnak cungah a chuahpimi hnahnawhnak tlawmternak caah pawngkam zohkhenhnak phunglam fek tein an zulh a hau.
