    • A process useful for protecting metal surfaces against corrosion in is presented involving: (a) forming a corrosion inhibitor having a compound corresponding to formula (I): where R1, R2 and R3 independently of one another represent an alkyl or hydroxyalkyl group containing 1 to 4 carbon atoms, an aryl or alkylaryl group or a group corresponding to formula (II): A− is an anion, n is the number 2 or 3, p is a number of 1 to 3 and R5 is an alkyl or alkenyl group containing 7 to 23 carbon atoms and 0, 1, 2 or 3 double bonds, and R4 is a group corresponding to formula (II) or (III): where R1, R2 and R3 are as defined above and Z is a group —(CH2)m— or a group corresponding to formula (IV):  m is an integer of 1 to 6, X is a group NH or an oxygen atom and D is a dimer fatty acid residue containing on average 36 to 54 carbon atoms; (b) combining the corrosion inhibitor with liquid aqueous, liquid non-aqueous or gaseous media; and (c) contacting the corrosion inhibitor with metal. The corrosion inhibitor used in the is biodegradable and shows low aquatic toxicity.

    • The invention relates to a process for facilitating the disposal of flowable and pumpable working fluids based on emulsifiers containing W/O invert emulsions--more particularly corresponding auxiliaries of the type used in geological exploration, such as oil-based w/o invert drilling muds--and for the simplified cleaning of solid surfaces soiled therewith, if desired using flowable spraying aids, the process being characterized in that, by selecting and adapting the emulsifiers/emulsifier systems to the oil phase of the invert emulsion, temperature-controlled phase inversion is achieved at temperatures below the in-use temperatures of the w/o invert emulsions, but above the freezing point of the aqueous phase and in that disposal and cleaning are carried out at temperatures in and/or below the phase inversion temperature range. The invention also relates to the use of this process for the cleaning and disposal of roc cuttings covered with residual drilling mud from geological exploration during and/or preferably before their on-shore or off-shore dumping
