(式中、R8及びR9は同じ又は異なり、直鎖又は分岐のアルキル、シクロアルキル、アラルキル、アルカリール、又は上述の基のいずれかの、実質的にヒドロカルビル基の置換誘導体でもよく、各酸のR8及びR9基は、平均して、少なくとも3個の炭素原子を有する)の酸によって例示することができる。「実質的にヒドロカルビル」とは、基の炭化水素特性に実質的に影響を及ぼさない置換基を含む、例えば基部分1個当たり、例えば、エーテル、エステル、チオ、ニトロ又はハロゲンなどの置換基を1〜4個含む基を意味する。
2−アミノインダン(39.8g、300mmol)、2−ブロモインダン(65g、329mol)及び50%のNaOH(22mL)のトルエン(220mL)中の混合物を、45分間窒素でパージした。ビス(トリ−t−ブチルホスフィン)パラジウム(0)(1.6g、3.2mmol)及び臭化セチルトリメチルアンモニウム(0.56g、1.6mmol)を、窒素流下でフラスコに加えた。次いで、混合物を約100℃で4日間加熱し、次いで撹拌せずに終夜冷却させた。混合物を、セライトを通して濾過し、濾過ケーキをトルエンですすいだ。溶液を水(100mL)で抽出し、真空蒸留で濃縮した。得られた残渣を短路クーゲルロール装置上で、真空蒸留した。前留分を最大140℃、0.89Tで回収した。さらに(0.6〜3.6Tで)160℃に加熱した後、生成物(73g、収率97%)を蒸留して淡い黄色がかった油とし、そのまま固体化させた。GC/FID分析は、純度99%(面積%)を示した。生成物を、ヘキサン中でさらに再結晶させて、無色の固体を得た。この反応を、全体的に、以下のスキームIに示す。

SAE10W−30モーターオイル配合物の調製
表2に示すSAE10W−30モーターオイル配合物を、どの種類の酸化防止剤も加えずに調製した。
SAE10W−30モーターオイル配合物の調製
表2に示すSAE10W−30モーターオイル配合物に、1重量パーセントのアルキル化ジフェニルアミン(Naugalube438Lとして市販されている)を混合した。Naugalube438Lは、一般式:
に示すように、モノ−C9アルキル化DPA、ジ−C9アルキル化DPA、及びある種のトリ−C9アルキル化DPAを含めた、C9オレフィンアルキル化ジフェニルアミン(DPA)の複合混合物である。
中高温熱酸化エンジンオイル模擬試験
中高温熱酸化エンジンオイル模擬試験(TEOST MHT(登録商標)、ASTMD7097、この全体を参照により本明細書に組み込む)を行い、モーターエンジンオイルのデポジット形成傾向を測定した。エンジンオイル配合物の安定化において、本発明の添加剤の改善された熱デポジット制御が、MHT TEOSTによってはっきりと示されている。この試験は、熱酸化及び触媒条件化で8.5mlの試験油の反復流路に連続して応力を加えることによって、特別に作製した鋼棒上で形成されたデポジットの質量を測定する。使用した器具は、Tannas Co.製であり、0.15(x+16)mgの典型的な再現性(但し、xは2回以上の反復試験結果の平均を意味する)を有する。TEOST試験条件を表3に記載する。得られたデポジットの量が少ないほど、油の酸化安定性が良い。この試験の結果を表4に示す。
