This standard specifies the test method for petroleum wax water-soluble acids or bases, applicable to paraffin wax and microcrystalline wax. A series of normative documents are cited, including the preparation of reagents and the determination method of paraffin wax melting point. The method outline includes mixing the sample with quantitative distillation water and heating, so that the water-soluble acid or base dissolves in the aqueous phase, and then using an indicator to observe the change of the aqueous solution Color to determine whether the sample contains water-soluble acids or bases. Reagents and materials include methyl orange and phenolphthalein indicator, distillation water, etc. Instruments and equipment include conicalflask, testtube, water bath, day and so on. Before using this standard, users should establish appropriate safety and protective measures and determine the applicability of relevant regulations.
