Automotive fuels - Information on aniline, N-methyl aniline, N-ethyl aniline, N,N di-methyl aniline and secondary-butyl acetate when used as blending components in unleaded petrol

This document is intended to draw attention to the potential technical consequences on engine parts and fuel systems when some types of chemical compounds are used as blending components in unleaded petrol.
The chemical compounds addressed specifically in this document are: secondary- Butyl acetate, Aniline and its derivatives such N-Methyl Aniline, N-Ethyl Aniline and di-Metyl Aniline.
Other chemical compounds are not addressed in this document, however attention is drawn to clause 5.4 of EN 228 which requires that unleaded petrol shall be free from any adulterant or contaminant that can render the fuel unacceptable for use. Thus when considering blending of other chemical compounds, care should be taken to ensure they are fit for use in order to comply with this requirement.
This document does not address environmental and/or health related issues. These aspects are beyond the scope of CEN/TC19 activities.

European foreword
This document (CEN/TR 17491:2020) has been prepared by Technical Committee CEN/TC 19 “Gaseous
and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin”, the
secretariat of which is held by NEN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
1 Scope
This document is intended to inform about the potential technical consequences on engine parts and
fuel systems when some types of chemical compounds are used as blending components in unleaded
petrol. This document is not meant to intentionally limit market fuel development.
The chemical compounds addressed, specifically, in this document are:
— sec-butyl acetate (SBA) (CAS 105-46-4),
— aniline (CAS 62-53-3),
— N-methyl aniline (NMA) (CAS 100-61-8),
— N-ethyl aniline (NEA) (CAS 103-69-5), and
— N,N di-methyl aniline (DMA) (CAS 121-69-7).
Other chemical compounds are not addressed in this document, however, attention is drawn to EN 228,
which requires that unleaded petrol be free from any adulterant or contaminant that can render the fuel
unacceptable for use.
