- the degree of amidation is inversely proportional to the acid number.
- poly (alkyl (meth) acrylate As poly (alkyl (meth) acrylate), the compounds listed in the table were used as 50% settings in higher-boiling solvent. The K values are determined according to Ubbelohde at 25 ° C. in 5% strength toluene solution. Characterization of the poly (acrylates) used C1 Poly (octadecyl acrylate), K value 32 C2 Poly (dodecyl acrylate), K value 35.6 C3 Poly (phenyl acrylate), K value 22.4
- CFPP value (according to EN 116, in ° C) of various biofuels according to the above table was determined after addition of 1200 ppm, 1500 ppm and 2000 ppm of additive mixture. Percentages refer to parts by weight in the respective mixtures.
- Tables 5 to 7 show that comb polymers with the factor Q according to the invention achieve excellent CFPP reductions even at low dosing rates and offer additional potential at higher dosing rates.
- the CFPP value is used to determine the resistance to cold corrosion of an oil according to DIN EN 116 before and after a standardized cold change treatment compared.
- the additiviere oil sample is reheated to room temperature without shaking. From each of the upper, middle and lower sections of the cylinder a sample of 50 ml is drawn for CFPP measurements. A difference between the mean values of the CFPP values after storage to the CFPP value before storage and between the individual phases of less than 3 K shows a good resistance to cold flashes.
