Description
(A)過半量で存在する潤滑粘度の油、および

「活性成分」または「(a.i.)」は希釈剤または溶媒ではない添加剤材料を指し;
「含む」または任意の同種の単語は、言明した特徴、ステップ、または整数もしくは構成要素の存在を規定するが、1つまたは複数のその他の特徴、ステップ、整数、構成要素、またはそれらの群の存在または付加を排除しない。表現「からなる」または「から本質的になる」または同種の表現は、「含む」または同種の用語の範囲内に包含されてもよく、この場合、「から本質的になる」は、その表現が適用される組成物の特徴に実質的に影響を及ぼさない物質を含むことを許容し;
「ヒドロカルビル」は、炭素原子を介して化合物の残りの部分に結合されている、水素および炭素原子を含む化合物の化学基を意味する。該基は、炭素および水素以外の1つまたは複数の原子(「ヘテロ原子」)を含むことができる(但し、それらのヘテロ原子が、該基の本質的にヒドロカルビル的性質に影響を及ぼさないなら);
本明細書中で使用される「油溶性」または「油分散性」、または同種の用語は、化合物または添加剤が、油中にあらゆる比率で可溶性、溶解性、混和性であるか、あるいは懸濁される能力を有することを必ずしも意味しない。しかし、これらの用語は、それらの化合物または添加剤が、例えば、油が採用される状況下でそれらの意図した効果を発揮するのに十分な程度まで、油中に溶解または安定的に分散できることを意味する。さらに、その他の添加剤のさらなる組込みは、所望なら、より高濃度の特定添加剤の組込みをも許容し;
「内燃機関の排気ガス中に持ち込まれるリンおよび/またはリン含有化合物の濃度を低減すること」は、本発明の比較潤滑油において添加剤成分(B)をその全体で五硫化リンと式ROHのアルコール(ここで、ROHは、成分(B)を製造するのに使用されるものと同一である)との反応生成物であるジチオリン酸の油溶性亜鉛塩と取り替えた類似の潤滑油組成物と比較して、本明細書に記載のようにシーケンスIII G試験法に従って測定した場合の本発明の潤滑油による高められたリン保持力を意味し;
「過半量」は組成物の50質量%を超えることを意味し;
「少量」は、組成物の50質量%未満を意味し;
「TBN」は、ATM D2896によって測定されるような全塩基価を意味し;
「リン含有量」は、ASTM D5185によって測定され;
「硫黄含有量」は、ASTM D2622によって測定され;
「硫酸灰分含有量」は、ASTM D874によって測定され;
「リン保持力」は、シーケンスIII G試験法によって測定される。
潤滑粘度の油(時には、「ベースストック」または「基油」と呼ばれる)は、潤滑油の主な液体成分であり、その中に、例えば添加剤およびおそらくはその他の油をブレンドして、最終潤滑油(または潤滑油組成物)を製造する。
この成分は、塩基性亜鉛化合物をジチオリン酸と反応させることによって得ることができ、該ジチオリン酸は、五硫化リンを、式ROHの少なくとも1種の第1アルコール(ここで、Rは、少なくとも4個の炭素原子を有する脂肪族ヒドロカルビル基である)および多価アルコールのエステルである少なくとも1種の第2アルコールからなる混合物と反応させることによって得ることができる。
エンジンを指定時間(t)稼動させた後に潤滑油組成物、特にクランクケース潤滑油中に保持されるリンの量は、次式から計算することができ、
添加剤成分(B)とは異なる、存在してもよい補助添加剤を、典型的な有効量と共に次に記載する。記載したすべての値は、活性成分の質量パーセントとして示される。
