Description
【0001】
【発明の属する技術分野】
本発明は燃料油用清浄剤及び燃料油組成物に関し、詳しくは燃料油に対する溶解性に優れ、特にガソリンエンジンの吸気弁及び燃焼室内の清浄性にすぐれた燃料油用清浄剤及び燃料油組成物に関する。
【0002】
【従来の技術】
内燃エンジンの吸気弁及び燃焼室に沈降物を生じるとエンジン機能の低下、排ガス等に悪影響を及ぼす。このため、沈降物の除去、付着防止、浄化等の清浄効果を目的に、燃料油には各種添加剤が、添加されている。
【0003】
例えば、米国特許第3440029号、ヨーロッパ特許第310875号、特公昭56−48556号、特開平3−128933号特開平3−229797号、特開平6−322381号各公報などに、モノアミノエーテル化合物系添加剤やポリアミノエーテル化合物系添加剤が開示されている。
この種のアミノエーテル化合物は、原則的には良好な清浄効果を発揮するが、加減速が頻繁な過酷な運転条件下では、その清浄効果は不十分であり、さらなる性能向上が望まれている。又、これら化合物の反応生成物中に塩素などのハロゲンが残留するなどの問題もある。ハロゲン(特に塩素)が残存すると酸性ガス等が発生し、エンジン内において金属腐食等の問題が生じる可能性がある。
【0004】
【発明が解決しようとする課題】
従って本発明の目的は、清浄性に優れ、金属等の材質腐食の心配のない燃料油用清浄剤及び燃料油組成物を提供することにある。
【0005】
【課題を解決するための手段】
上記目的を達成するために鋭意検討した結果、特定のポリエーテル化合物が燃料油用清浄剤及び燃料油組成物として優れた効果を発揮することを見いだし本発明に到達した。
すなわち、下記一般式(1)で表されるポリエーテル化合物(A)からなり、該ポリエーテル化合物(A)の重量平均分子量が1300〜3500、水酸基価が15〜40、溶解性パラメーター(SP値)が8.8〜9.4、HLB値が2.5〜6.0、40℃粘度が700mm2/s以下、塩素含有量が10ppm以下である燃料油用清浄剤、及び、燃料油組成物である。
一般式
H2N−(C2H4O)m−(XO)n−H (1)
[式中、Xは炭素数2〜4のアルキレン基;mは1〜3の整数、nは20〜50の整数を示す。]
【0006】
【発明の実施の形態】
以下、これらについて詳細に説明する。
本発明のポリエーテル化合物(A)である、一般式(1)において、Xは炭素数2〜4のアルキレン基(エチレン基、プロピレン基、ブチレン基)であり、好ましくは、プロピレン基、ブチレン基である。炭素数1の場合は燃料油への溶解性が劣る場合があり、炭素数が4を越えると清浄効果が弱くなる場合があり好ましくない。mは1〜3の整数であり、好ましくは、1である。nは20〜50の整数であり、好ましくは、25〜40である。20未満では、燃焼室の清浄効果が弱くなる場合があり、又、50を越えると吸気弁の清浄効果が弱くなる場合があり好ましくない。
【0007】
ポリエーテル化合物(A)の重量平均分子量は、1300〜3500であり、好ましくは、1500〜3250、さらに好ましくは、1500〜3000である。1300未満では、燃焼室の清浄効果が弱くなる場合があり、又、3500を越えると吸気弁の清浄効果が弱くなる場合があり好ましくない。尚、本分子量は、ゲルパーミュエーションクロマトグラフィーによるポリエチレンに換算した重量平均分子量である。
【0008】
ポリエーテル化合物(A)の水酸基価は、15〜40であり、好ましくは、18〜35、さらに好ましくは、20〜30である。15未満では、燃焼室の清浄効果が弱くなる場合があり、又、40を越えると吸気弁の清浄効果が弱くなる場合があり好ましくない。
【0009】
ポリエーテル化合物(A)の溶解性パラメーター(SP値)は、8.8〜9.4であり、好ましくは、8.8〜9.2、さらに好ましくは8.8〜9.0である。8.8未満、又は、9.4を越えると燃料油への溶解性、及び、清浄効果が弱くなる場合があり好ましくない。尚、本発明の溶解性パラメーター(SP値)は、Fedors法[Polym.Eng.Sci.14(2)152,(1974)]によって算出される値である。
【0010】
ポリエーテル化合物(A)のHLB値は、2.5〜6.0であり、好ましくは、3.0〜5.5、さらに好ましくは、3.5〜5.0である。2.5未満ではガソリンへの溶解性、及び、清浄効果が弱くなる場合があり、又、6.0を越えると水との分離性が弱くなり、タンク・エンジン等において、腐食や錆等の問題が発生する場合があり好ましくない。尚、本発明のHLB値は、小田法[小田、寺田共箸、「界面活性剤の合成と其応用」501頁、槇書店(1957)発行に記載]によって算出される値である。
【0011】
ポリエーテル化合物(A)の40℃粘度は、700mm2/s以下であり、好ましくは、500mm2/s以下、さらに好ましくは、350mm2/s以下である。
700mm2/sを越えると清浄効果が弱くなる場合があり好ましくない。
又、100℃粘度については特に限定はないが、通常100mm2/s以下であり、好ましくは、80mm2/s以下、さらに好ましくは50mm2/s以下である。
【0012】
ポリエーテル化合物(A)中に含有される塩素量は、10ppm以下であり、好ましくは、7ppm以下、さらに好ましくは5ppm以下である。10ppmを越えるとエンジン内において金属腐食等の問題が発生する場合があり好ましくない。
【0013】
ポリエーテル化合物(A)の合成方法としては特に限定はないが、危険な化合物(水素ガス、アンモニア、ハロゲン等)を使用しない点から、好ましくは、イミノ基含有ポリエーテル化合物の加水分解による合成法である。さらに好ましくは、下記一般式(2)に示されるイミノ基含有ポリエーテル化合物の加水分解による合成法である。
一般式
R1R2C=N−(C2H4O)m−(XO)n−H (2)
[式中、R1及びR2は炭素数1〜8の炭化水素基を示し、R1及びR2の少なくとも一つの基のイミノ基に隣接する炭素原子は、2級炭素又は3級炭素である。
Xは炭素数2〜4のアルキレン基、mは1〜3の整数、nは20〜50の整数を示す。]
【0014】
R1及びR2における炭素数1〜8の炭化水素基としては、メチル基、エチル基、n−プロピル基、イソプロピル基、イソブチル基、t−ブチル基、イソオクチル基、2−エチルヘキシル基、1−フェニルエチル基等が挙げられる。炭素数2〜4のアルキレン基は、前記したものと同じである。
該イミノ基含有エーテル化合物は、例えば、1級アミノ基と水酸基とを併せ持つ化合物(例えばモノエタノールアミン)とケトンを加熱、脱水反応して活性水素基含有イミノ化合物を得、その後エーテル化させること等により合成することができる。
用いられるケトンとしては、メチルイソブチルケトン、ジイソプロピルケトン、ジイソブチルケトン、ジ−t−ブチルケトン等が挙げられる。
【0015】
イミノ化反応は、通常の方法により行うことができる。反応例としては、水酸基含有1級アミン化合物中の1級アミノ基に対して、0.5〜2当量のケトン存在下、100〜140℃に加熱、脱水反応させることで容易に活性水素基含有イミノ化合物が得られる。尚、この反応においては、水と共沸するトルエンのような還流溶媒が共存しても良い。
【0016】
エーテル化反応の方法としては水酸基含有ケチミン化合物を必要により適当な溶媒(トルエン、キシレン等)中、触媒(例えば水酸化ナトリウム、水酸化カリウム等)の存在下、加熱しながらアルキレンオキサイドを加えることにより合成できる。反応温度としては70〜140℃、好ましくは90〜130℃である。
【0017】
該反応の際、立体障害の小さなケトン(アセトン、メチルエチルケトン、ジエチルケトン等)から得られる活性水素基含有ケチミン化合物では、反応温度が80℃より高くなると、イミノ基脱離によると考えられる副反応が進行し、副生成物(2級アミン化合物等)が生成する場合があるが、本発明のように立体障害の大きなケトンでイミノ化した活性水素基含有ケチミン化合物では、副反応を極めて低いレベルに抑制でき、最終的に清浄性に優れた化合物が得られる。
【0018】
上記イミノ基含有エーテル化合物を加水分解することで1級アミノ基と水酸基とを有した一般式(1)で表されるポリエーテル化合物(A)が得られる。
一般式
H2N−(C2H4O)m−(AO)n−H (1)
[式中、Aは炭素数2〜4の炭化水素基;mは1〜3の整数、nは20〜50の整数を示す。]
【0019】
該加水分解は、例えば、過剰の水存在下、加熱処理することで行われる。反応温度としては90〜140℃、好ましくは、95〜125℃である。
【0020】
該1級アミノ基含有エーテル化合物(A)の熱分解減少量については特に限定はないが、清浄性の点から通常、室温から25℃/分の昇温速度で加熱した場合、200℃での熱分解減少量が5重量%未満、300℃での熱分解減少量が95重量%以上、好ましくは、200℃での熱分解減少量が3重量%未満、300℃での熱分解減少量が97重量%以上、さらに、好ましくは、200℃での熱分解減少量が1重量%未満、300℃での熱分解減少量が99重量%以上である。
【0021】

【0022】
本発明の燃料油清浄剤に含有される第二成分(B)の量は、(B)/[(A)+(B)]の重量比として、通常、0〜0.97、好ましくは、0.10〜0.95である。
【0023】
本発明のポリエーテル化合物(A)からなる燃料油添加剤は、種々の燃料油、例えば石油留分、アルコール類、LNG、植物油等の内燃機関の燃料として使用し得る全てに対して使用可能である。好ましくは、内燃機関用ガソリンや軽油に添加した場合であり、ガソリンエンジンの吸気系統や燃焼室の清浄性、及び、ディーゼルエンジンの噴射ノズルや燃焼室の清浄性に極めて優れた性能を発揮する。さらに好ましくは、内燃機関用ガソリンに添加した場合である。

The alkylene group having 2 to 4 carbon atoms is the same as described above.
The imino group-containing ether compound is, for example, a compound having both a primary amino group and a hydroxyl group (for example, monoethanolamine) and a ketone are heated and dehydrated to obtain an active hydrogen group-containing imino compound, and then etherified. Can be synthesized.
Examples of the ketone used include methyl isobutyl ketone, diisopropyl ketone, diisobutyl ketone, and di-t-butyl ketone.
