Description
本發明係關於α-烯烴、乙烯酯及不飽和α,β-羧酸酯之共聚物作為改良燃料及潤滑劑之耐冷性的添加劑的用途,以及含這些共聚物之燃料油類及包裝物。
在低溫下,烴類之組成物,特別是以含石蠟系蠟類(paraffinic wax)之中間餾出物型為底質者,例如柴油燃料及加熱用油,在其流動性質方面明顯降低。習知的是石蠟之結晶作用是中間餾出物之用途的限制因素。並且,重要的是要製備柴油燃料而其適於即將在車輛中使用時的溫度,亦即適應於周圍氣候。通常,在-10℃下之燃料的冷操作性在很多熱帶或溫帶國家是足夠的。但在冷氣候之國家諸如斯堪地那維亞國家、加拿大及北亞國家中,可以達到遠低於-20℃之燃料的使用溫度。這也適用於儲存在建築物(房子、公寓區塊)外之家用油類。中間餾出物型之燃料的冷操作性適當性是重要的,特別是用於引擎之冷啟動者。若該石蠟在槽底部結晶,則在啟動時彼可以被驅入燃料管線中且明顯地阻塞位於噴射系統(泵及噴射器)上游之過濾器及前過濾器。並且,當儲存家用油類時,石蠟沉澱至槽底部且可被驅動並阻塞泵的上游管線及鍋爐(噴嘴及過濾器)之供應系統的上游管線。明顯地,固體(例如石蠟晶體)之存在阻礙中間餾出物之正常循環。
為要改良其在引擎中或朝向鍋爐之流動性,已發展數種形式之添加劑。
在第一階段中,汽油工業致力於發展所謂之冷流動添加劑(冷流動改良劑或CFI),其促進石蠟晶體之分散且藉此防止晶體自動組織成會造成濾器孔阻塞之大體積晶格。這些添加劑基本上對限制過濾性溫度(LFT)及對傾點有作用,但不改良渾濁點。
先前技藝已描述很多CFI添加劑(參見例如US 3,048,479、US 3,627,838、US 3,790,359、US 3,961,961、EP 261 957),通常是乙烯及不飽和酯之共聚物,諸如乙烯/乙酸乙烯酯(ethylene/vinyl acetate,EVA)、乙烯/丙酸乙烯酯(EVP)、乙烯/乙酸乙烯酯(ethylene/vinyl ethanoate,EVE)、乙烯/甲基丙烯酸甲酯(EMMA)、及乙烯/反丁烯二酸烷酯共聚物。
為要改良標準CFIs之性質,先前技藝也建議乙烯/不飽和酯型之一般CFI添加劑與潤滑劑(單或多元醇類之單或多元羧酸酯類,例如參見EP 721 492),與抗沉澱劑(參見例如FR 2 490 669),與醚類(參見例如US 3,999,960、EP 187 488)之混合物。
也發現改良之CFI添加劑,其為衍生自多於3種不同單體之三元聚合物或共聚物。
例如,US 6,509,424描述一種在管狀反應器中製備乙烯及至少二種含有乙烯不飽和度之化合物(諸如乙烯酯類、(甲基)丙烯酸酯類、烷基乙烯基醚類)的三元聚合物的方法。這些三元聚合物可以用來作為改良石油及石油餾出物之冷流動的添加劑。
US 3,642,459描述包含40-89重量%之乙烯、10-40重量%之衍生自短鏈(C2
-C4
)羧酸的乙烯酯(諸如乙酸乙烯酯)、及具有C10
-C22
烷基鏈之不飽和單酯類之三元聚合物;這些三元聚合物被用來作為降低石油餾出物之傾點的添加劑及作為抗蠟劑且用於改良其過濾性。
US 4,156,434描述乙烯、乙酸乙烯酯及衍生自C12
-C24
醇之丙烯酸酯的三元聚合物,其降低合併有該三元聚合物之燃料的傾點,但並未提及這些添加劑對冷過濾性之改良。
WO 2005/054314描述可被使用之α-烯烴、乙烯酯及不飽和α,β-單羧酸酯的三元聚合物。三元聚合物中申請人所例舉之特佳者含有多於80莫耳%之乙烯及少於9莫耳%之乙酸乙烯酯。現在,這些含有少於9莫耳%之乙酸乙烯酯的三元聚合物雖然對含有多於18%之正石蠟的中間餾出物的LFT的降低有影響,但一方面其在溶解度上,且另一方面阻塞傾向(或室溫過濾性)上皆不能令人滿意:可破壞之濾器阻塞被指出。
EP 1 391 498描述改良中間餾出物之低溫流體性的添加劑,其是乙烯基聚合物(A),較佳是乙烯-乙烯基酯共聚物,其所用之不溶於己烷的材料的量在-20℃下超過60重量%且在10℃下少於30重量%;EP 1 391 498之實例清楚地顯示:共聚物及三元聚合物(所用之不溶於己烷的材料在-20℃下超過60重量%且在10℃下少於30重量%)之過濾性溫度(冷過濾器堵塞點(cold filter plug point,CFPP)),與具有相同比例之相同重複單元但所用之不溶於己烷之材料的量係在所要求之範圍之外的共聚物或三元聚合物相比,係被降低;例示之共聚物是EVA共聚物及乙烯-(乙酸乙烯酯)-(新癸酸乙烯酯或2-乙基己酸乙烯酯)三元聚合物。
對於添加劑仍有未解決之需要,以改良燃料之耐冷性(LFT及傾點),同時降低或甚至消除阻塞的風險,以避免用於引擎或鍋爐的供應系統(噴射系統及槽)的濾器的阻塞。
本發明係關於共聚物作為改良燃料之耐冷性之添加劑(CFI添加劑)的用途;這些共聚物含有衍生自至少一種α-烯烴、至少一種乙烯酯及至少一種不飽和α,β-單-羧酸酯的單元,且較佳是乙烯、乙酸乙烯酯及丙烯酸乙基-2-己酯之三元聚合物。

較佳地,可作為CFI添加劑之共聚物紀錄成四邊形ABCD,其中A、B、C及D代表該四邊形之頂點且對應於至少該乙烯酯及至少該不飽和α,β-單-羧酸酯之莫耳%:

[實施例]
在一管狀反應器中,乙烯、乙酸乙烯酯及丙烯酸乙基-2-己酯之三元聚合物藉由在1,400至2,500巴(140至250 MPa)之高壓下及在200至280℃之聚合溫度下的自由基聚合作用合成。該合成係藉由使用脂族醛(丙醛)以控制分子質量且藉由使用過氧化物作為聚合起始劑而進行。在以下表I中顯示該合成之三元聚合物之Mn及Mw以及其單體之百分比。
這些三元聚合物之改良耐冷性之能力藉由將彼合併於馬達氣油型(motor gasoil type)之二種餾出物(稱為GOM 1及GOM 2)而評估,在以下表2中將該二種餾出物特徵分組。
400 ppm重量之以下各共聚物被併入稱為GOM 1之馬達氣油型餾出物中,然後阻塞指數FBT(過濾器阻塞傾向Filter Blocking Tendency)依照IP 387標準測量。不含任何添加劑之GOM 1具有1.01之FBT阻塞指數。結果見到:在具有依本發明之三元聚合物17時,則GOM 1之阻塞傾向不會變差,亦即添加400 ppm之三元聚合物的GOM 1具有少於1.41之FBT。結果顯示於以下表3中。
併入GOM 1及GOM 2中的三元聚合物的耐冷性LFT效率在210 ppm濃度下測量;在表4中將結果分組。
結果見到:依本發明之三元聚合物17對於氣油GOM 1是最有效率的。再者,由表3中所得之結果見到:以400 ppm之量添加於GOM 1的三元聚合物17不使阻塞傾向變差。這在依WO 2005/054314之比較用三元聚合物6;7;16及18的情況中並非如此,這些比較用三元聚合物強烈地使依照IP387所測得之阻塞傾向變差且並未有如本發明之添加劑17一樣的LFT效率。
