propylene glycol methyl ether acetate
CAS: 84540-57-8; 108-65-6
Qaabka kiimikada: C6H12O3
Propylene glycol methyl ether acetate waa nooc dareere horumarsan. Unuggiisu waxa uu ka kooban yahay labada ether bond iyo carbonyl group, iyo kooxda carbonyl waxay sameeyaan qaab dhismeedka ester oo ka kooban alkyl group. Isla molecule-ka, waxa ku jira qaybo aan cirifka ahayn iyo qaybo ka mid ah qaybaha, kooxaha shaqada ee labadan qaybood maaha oo kaliya inay xakameeyaan oo iska celiyaan midba midka kale, laakiin sidoo kale waxay ciyaaraan doorkooda asalka ah. Sidaa darteed, waxay leedahay milmayn gaar ah oo loogu talagalay walxaha aan dabaylaha ahayn iyo kuwa polar labadaba. Propylene glycol methyl ether acetate waxaa lagu soo saaray esterification of propylene glycol methyl ether iyo glacial acetic acid iyadoo la isticmaalayo sulfuric acid sida kicinta. Waa dareere warshadeed horumarsan oo hooseeya oo hooseeya, wuxuu leeyahay awood xoog leh oo uu ku milmi karo walxaha polar-ka iyo kuwa aan-dabiiciga ahayn, oo ku habboon daahan heersare ah, dareeraha khad ee polymers kala duwan, oo ay ku jiraan aminomethyl ester, vinyl, polyester, acetate cellulose, resin alkyd, resin acrylic, resin epoxy iyo nitrocelluloses. Waxaa ka mid ah. Propylene glycol methyl ether propionate waa dareeraha ugu fiican ee rinjiga iyo khad, oo ku habboon polyester aan saturated ahayn, xabagta polyurethane, resin acrylic, resin epoxy iyo wixii la mid ah.
Sida laga soo xigtay "2023-2027 Shiinaha Propanediol methyl ether acetate (PMA) Mashruuca Study Study Feasibility Investment" sii daayay by Xinjie Industry Research Center, marxaladdan, Shiinaha propanediol methyl ether technology soo saarka Acetate ayaa si tartiib tartiib ah u hagaagtay, ay waxqabadka dhamaystiran ayaa si tartiib tartiib ah u hagaagtay, ay goobta codsiga ayaa si tartiib tartiib ah u horumariyo, iyo semicondu, suuqyada kale. Baahida suuqa ayaa si tartiib tartiib ah u kordheysa. Marka la eego asalkan, miisaanka suuqa ee propylene glycol methyl ether acetate ee Shiinaha ayaa muujinaya kor u kaca sanadba sanadka ka dambeeya. Laga soo bilaabo 2015 ilaa 2022, cabbirka suuqa ee propylene glycol methyl ether acetate ee Shiinaha wuxuu ka kordhay 2.261 bilyan yuan ilaa 3.397 bilyan yuan, iyadoo korodhka kobaca sanadlaha ah ee 5.99%. Waxaa ka mid ah, suuqa kiimikada ee Tianyin ayaa ku xisaabtamay saamiga ugu badan, isagoo gaaray 25.7%; Hualun Kiimikada ayaa raacday, oo xisaabinaysa 13.8% suuqa; Kaalinta saddexaad waxa ku jirta Jida Chemical, iyada oo saamiga suuqa ku leh 10.4%. Iyadoo horumarinta joogtada ah ee warshadaha propylene glycol methyl ether acetate ee Shiinaha, qaab dhismeedka awoodda ayaa si tartiib tartiib ah kor loogu qaadayaa, awoodda wax-soo-saarka dib-u-celinta ayaa si tartiib tartiib ah loo tirtiraa, iyo diiradda suuqa ayaa la filayaa inay sii korodho mustaqbalka.
Oktoobar 19-keedii, oraahda guriga propylene glycol methyl ether acetate waxay ahayd 9800 yuan/ton. Tilmaamaha propylene glycol methyl ether acetate: 200 kg / foosto 99.9% ka kooban heerka qaranka. Soo jeedintu waxay shaqaynaysaa 1 maalin Bixiyaha xigashada: Xiamen Xiangde Supreme Chemical Products Co., LTD.
Waqtigan xaadirka ah, iyada oo horumarinta daahan, khad, daabacaadda iyo midabaynta, dharka iyo warshadaha kale ee Shiinaha, baahida suuqa ee Shiinaha ee propylene glycol methyl ether acetate warshadaha waa sii kordhaya, iyo heerka wax soo saarka gudaha ee warshadaha propylene glycol methyl ether acetate ayaa sii kordhaya iyo sare. Si kastaba ha noqotee, tignoolajiyada wax soo saarka ee darajada elektiroonigga ah iyo xitaa heerka semiconductor propylene glycol methyl ether acetate waa mid adag. Waqtigan xaadirka ah, shirkadaha maxalliga ah ee Shiinaha ee propylene glycol methyl ether acetate waxay leeyihiin boos beddelka suuqa oo weyn oo goobtan ah. Qalabka elektiroonigga ah ee propylene glycol methyl ether iyo propylene glycol methyl ether acetate waxaa loo isticmaali karaa dareeraha dareeraha ah, nadiifinta ama nadiifinta dareeraha soo saarista qaybaha elektiroonigga ah oo ay ku jiraan semiconductors, substrates photoresist, taarikada naxaasta ah, bandhigyada crystal dareeraha iyo meelaha kale. Shiinaha ayaa dhawaan soo bandhigay tiro ka mid ah qorshaha "afar iyo toban" qorshe ayaa lagu xusay si ay u dhiiri horumarinta semiconductor iyo warshadaha kale-teknoolajiyada sare warshadaha, Shiinaha ee propylene glycol methyl ether acetate warshadaha ama waxay awoodi doonaan in ay qaataan dabaysha bari ee siyaasadda, kor u horumarinta iyo ballaarinta heerka elektiroonigga ah propylene glycol methyl ether acetate, iyada oo mustaqbalka soo dejinta ee warshadaha elektiroonigga ah ether glycol kororka glycol ee China propylene propylene glycol. waxay abuuri doontaa faa'iido badan oo faa'iido leh warshadaha, oo leh qiimo maalgashi oo weyn.
