Description
Technical field
The present invention relates to method and device that a kind of warm air drying prepares powdered fat acid methyl ester sulfonate.
Background technology
Methyl sodiosul foaliphatate (SodiumFattyAcidMethylEstersulfonate is called for short MES) take plam oil as raw material, obtain fatty acid methyl ester through transesterify, hydrogenation, then through oversulfonate, resterification, in and the new nonionic surfactant of an excellent property that obtains of operation.
It is good, gentle, nontoxic and to advantages such as human body pungency are low that MES has detersive power, and without phosphorus characteristic is better than petroleum-based products, in the all-round popularization period of current free phosphate detergent, MES is specially adapted to produce without phosphorus and low-phosphorous environment-friendly type articles for washing, particularly non-phosphide detergent.But there is C-O-C ester bond in MES structure, the sodium soap sodium sulfonate (abbreviation disodium salt) that very easily saponification becomes water-soluble and detersive power is poor under alkalescence, water existent condition; Before current washing powder in proportioning process, widely use the alkaline assistants such as sodium silicate, sodium carbonate, 4A zeolite to improve washing powder over-all properties, therefore before MES washing powder, directly cannot use MES in proportioning process.Allotment of labor's skill after current more employing, namely first prepares washing powder original washing powder and MES powder respectively, by after join the washing powder that mix obtains containing MES.But the alkyl carbon chain of commercialization MES oleophilic group is based on ten six carbon atoms and 18 carbon atoms, and its fusing point, at about 43 DEG C, is just in molten state, is easily bonded to block more than 45 DEG C, needing could powder-like product by special disintegrating process.Such as, described in CN1931987A, by dried sheet MES by freezing treatment, then broken, sieving obtains powdery MES, for preparing burden after washing powder.But this product is used for washing powder also deposits problem both ways: 1, the particle that obtains of this disintegrating process is inconsistent with washing powder particle, easily occurs uneven problem, causes quality product to fluctuate greatly; 2, the krafft point of MES higher (about 25 DEG C), easily occurs when cold water washing, and washing has completed but white granular MES is also attached on the undissolved situation of clothing, affects washing effect.
Summary of the invention
Technical problem to be solved by this invention is the deficiency overcoming above-mentioned background technology, a kind of method providing warm air drying to prepare powdery MES and device, the MES granularity that described method obtains should be basically identical with washing powder, to improve the stability of washing powder product, and powdered granule is the hollow shape of good fluidity, greatly increase with specific surface area when making dissolving, obviously improve the solvability of MES powder, effectively play the washing effect of product; Described device should have simple and compact for structure, lower-cost feature.
