    Abstract: Tertiary alkyl acrylates or methacrylates of the formula wherein R1 denotes an H atom or the -CH3 group and the R2 radicals which may be the same or different denote an alkyl group having from 1 to 4 C atoms, are prepared by reacting acrylic or methacrylic acid with a tertiary olefin of formula where R2 has the above meaning and R3 denotes an alkylidene group with 1 to 4 C atoms, in the presence of an active bleaching earth containing from 0.005 to 0.1 milliequivalents per gram of free titratable acid at atmospheric or superatmospheric pressure and at a temperature of from 0 DEG C. to 40 DEG C. A suitable bleaching earth comprises 50 to 70% of SiO2, 10 to 30% of Al2O3, 2 to 8% of Fe2O3, 1 to 9% of MgO and small amounts of the oxides of the other alkaline earth metals (all percentages are by weight). Examples describe the production of tertiary-butyl acrylate.

    Abstract: A diesel fuel contains 0.1 to 2% (vol.) of a nitrate of a hydroxycarboxylic ester. Those preferred have the formula R1 being hydrogen, an aliphatic or an aromatic radical; R2 being hydrogen, an aliphatic or an aromatic radical; and R3 an aliphatic or an aromatic radical. Specified nitrates are those of methyl ethyl and isopropyl lactate, and that of methyl glycolate, acid urethyl hydroxy isobutyrate.
