Kiimikooyinka Aroma Eugenol oo Tayo Sare leh

Macluumaadka Alaabta

Eugenol, magaca kiimikada 4-allyl-2-methoxyphenol, waa mid ka mid ah Ether Compounds , sidoo kale waa mid ka mid ah Ether Compounds, formula kiimikaad ee C10H12O2, aan midab lahayn in dareere huruud ah iftiin, wax yar ku milmay biyaha, milmi in ethanol, acetone, ethyl acetate, ethyl acetate, chloroform wakiilka ugu weyn ee organic loo isticmaalo. Diyaarinta lilacs, balsam fir, carnations iyo saliidaha kale ee muhiimka ah, laakiin sidoo kale waxaa loo isticmaali karaa sida dhir udgoon oo la cuni karo, laakiin sidoo kale waxaa loo isticmaali karaa sida cayayaanka iyo ilaalinta.

Meesha dhalaalka: -12 ~ -10 ℃
Barta karkarinta: 254 ℃
Tusmada dib-u-celinta: 1.541 (20 ℃)
Muuqashada: dareere huruud ah oo aan midab lahayn
Solubility: wax yar ku milmay biyaha, ku milma ethanol, acetone, ethyl acetate, ethyl ether, chloroform iyo dareerayaasha kale ee organic.

Eugenol waxa uu si dabiici ah ugu jiraa saliidaha lagama maarmaanka ah sida saliidda caleenta ah, saliidda basil ee basil iyo saliidda qorfaha, iwm. Waqtigan xaadirka ah, wax soo saarka warshadaha ee eugenol, inta badan ka saliidaha lagama maarmaanka ah eugenol-hodan iyada oo loo marayo daaweynta alkali ee hal go'doon iyo helay. Sida caadiga ah la xal sodium hydroxide daray in saliid kala soocay, kululaynta iyo walaaqaya, sabeyn doonaa in dusha dareeraha ah ee qaybta non-phenolic ee saliidda la soo saaridda dareere ama uumi uumi, ka dibna ku dar acidification of cusbo sodium si aad u hesho eugenol ceeriin, lagu maydhay biyo si dhexdhexaad ah, ka dibna vacuum distillation la heli karaa by eugenol saafi ah. Habka synthetic si loo helo eugenol, guaiacol waxaa loo isticmaali karaa sida alaabta ceeriin, isticmaalka allyl chloride, alyl alkohol iyo guaiacol kale oo toos ah (patentkii hore ee Midowga Soofiyeeti 352872; US Patent 3929904). Habka synthetic ee eugenol, falcelin dhinaca kale ah, taasoo keentay kala-soocidda iyo nadiifinta ayaa aad u adag, oo saameeya tayada alaabta, si loo hagaajiyo oo loo hagaajiyo mustaqbalka. Eugenol waxaa loo isticmaali karaa dhadhanka cadarka iyo noocyo kala duwan oo dhadhan isqurxin ah iyo qaabaynta dhadhanka saabuunta, qaddarka 20% ama ka yar. Intaa waxaa dheer, waxaa sidoo kale loo isticmaali karaa samaynta dhadhanka la cuni karo.

Macluumaadka shirkadda

Waxyaalaha ay shirkadu soo dejiso iyo wax-soo-saarka dhoofinta ugu badan waxaa ka mid ah

(1) Daaweynta Biyaha: Hababka hysical P sidoo kale waxaa ka mid ah roobka, waa in la ogolaado wasakhda cufjiitada gaarka ah ee ka yar inay sabeeyaan biyaha dusheeda si ay uga kalluumaystaan, ama wasakhda roobabka cufisjiidadka gaarka ah ee hoose, ka dibna la helo. Habka kiimikooyinka waa in la isticmaalo noocyo kala duwan oo kiimikooyin ah oo ku jira wasakhda biyaha galay walxaha waxyeellada yar, ama wasakhda la ururiyey, taariikhda ugu dheer ee hababka daaweynta kiimikada waa in la tixgeliyaa in lagu daro biyaha leh alum, ururinta wasakhda biyaha, mugga ayaa noqda mid weyn, waxaa loo isticmaali karaa sifeynta, ka saarista wasakhda.

(2) Alaabta caagga ah: Marka alaabta caagga ah la qaabeeyo, ka dib marka lagu cadaadiyo cadaadiska sare, isku xirnaanta elastomer lama baabi'in karo, taas oo inta badan soo saarta hoos u dhac aan degganeyn marka badeecada laga soo saaro caaryada (heerka dhimista caaggu wuu kala duwan yahay iyadoo ku xiran nooca caag), kaas oo kaliya la fududeyn karo oo la dejin karo muddo cayiman ka dib. Sidaa darteed, marka naqshadaynta alaabta caag ah ee bilawga, iyada oo aan loo eegin caanaha ama caaryada, waxay u baahan yihiin in si taxadar leh loo xisaabiyo si ay u dhigmaan, haddii kale, way sahlan tahay in la soo saaro cabbirka alaabta aan degganeyn, taasoo keentay tayada alaabta hooseysa.
