Preparation of basic aluminium halides |
| abstract |
The disclosure concerns a process for the manufacture of basic aluminium chlorides in powder form for antiperspirant use which have an aluminium:chloride molar ratio of 1.7:1 to 2.2:1 and has a Band III fraction of at least 20% as determined by a chromatographic procedure. The disclosure centers on the finding of advantageous reaction conditions for the known reaction between aluminium powder and an aqueous aluminium chloride solution. The temperature of reaction is 50 DEG to 105 DEG C. and the final aluminium concentration of the solution is 7.5% to 13%. It has been discovered that if this reaction is carried out sufficiently rapidly a solution of a basic aluminium chloride is produced having a Band III fraction of at least 20%. The disclosure shows the influence of the grade of aluminium and manner of conducting the reaction on reaction time. The solution obtained is dried, preferably spray dried or freeze dried, to give the powder. |
