Testing of the aqueous solution of BTMAC is technically impossible. Testing of solid BTMAC by laser diffraction is technically impossible, because solid BTMAc is very hygroscopic.
Over 95 % of the BTMAC is produced and marketed as 60% aqueous
solution. Particle size distribution testing of that material is thus
About 10 t/a are produced and marketed as solid BTMAC. Solid BTMAC
is very hygroscopic and the wet crystals stick together in smaller and
bigger lumps when exposed to the air. These lumps cannot be analysed by
laser diffraction due to the moisture in the substances. Moisture
droplets are formed in a dispersing solvent, which interfere with the
measurement of the particle size of the crystals. Sieving is not an
alternative since the substance sticks to the sieves.
Based on this it is concluded that it is technically not possible
to determine the particle size distribution of these substances in the
