Compounds of the general formula (I) 1 where R1, R2 and R3 are independently hydrogen, cyclohexyl or phenyl, with the proviso that at least one of R1 to R3 is not hydrogen, R4 and R5 are independently methyl or hydrogen, and n is from 21 to 40, which are useful as biodegradable dispersants having good dispersing properties for active pharmaceutical and agrochemical components.
摘要:
A novel aqueous dye-accelerant composition that allows for the effective and rapid reaction of a dye with the fibers of a substrate such that the dye becomes evenly attached to the substrate within seconds is provided. The dye-accelerant composition generally comprises: an organic solvent; at least one dispersing agent; a chelating agent; and a vehicle. In another embodiment, a dyeing process utilizing the dye-accelerant composition, which includes five primary treatment processes: a pre-treatment process, a bleaching process, a neutralize and dye accelerant process, a dyeing process, and a dye stop or fixing process is provided.

The present invention relates to novel compounds of the formula ##STR1## wherein R.sub.1 is an alkyl group, M.sup.+ is a cation, R.sub.2 is an alkylene oxide and n is an integer from 1 to 4. Surfactant compositions containing these novel compounds, the process of preparing these novel compounds as well as the methods of using these surfactant compounds in enhanced oil recovery, as emulsifiers, in emulsion polymerization, as hydrotropes, in foamed drilling fluids, as dye carriers, as textile detergents, as foaming agents for concrete formation and as fiber lubricants are also disclosed.
摘要:
Mixture of dyeing assistants containing(A) an acid ester, or salts thereof, of an alkylene oxide adduct of the formula ##STR1## in which V is hydrogen or methyl, X is the acid radical of an inorganic acid containing oxygen, or the radical of an organic acid and Y is C.sub.1 -C.sub.12 alkyl, aryl or aralkyl, "alkylene" is the ethylene or propylene radical and m is 1 to 3, m.sub.1 is 1 or 2 and n is 4 to 50,(B) a nonionic surfactant containing polyglycol ether groups, and(C) an aliphatic or aromatic carboxylic acid ester, an alkylbenzene, tetralin or a mixture of these substances.The mixture of assistants is employed in the dyeing of synthetic fibre materials, in particular textile material containing polyester fibres, for increasing the rate of migration of disperse dyes.
摘要:
Aqueous dyestuff dispersions which contain water-insoluble dyestuffs and water-soluble oxyalkylation products of compounds which are obtainable by the addition of styrene or its derivatives onto phenols or naphthols, or derivatives of such oxyalkylation products, are suitable for pigmenting natural or synthetic materials.
摘要:
The present invention provides a novel pretreating agent to improve the effect of ink-jet printing on polyester fabric and its application, and this invention belongs to the field of digital ink-jet printing. Stirring the dispersing agent, which includes many procedures of wetting agent and deionized water in a stirrer, adding nano-porous oxide dispersoid. Furthermore, keep stirring for 30 min and put the mixture in a sand mill to grinded for 2 h, then nano-porous oxide dispersoid is eventually got. The nano-porous oxide dispersoid work as pretreating agent, which used in the polyester fabric, is treated like pretreating agent during the padding process. By applying this technique into double-sided permeation ink-jet printing and direct-injection ink-jet printing, its pattern's definition, colour depth and colour saturation could be remarkable enhanced. This method has many advantages such as the craft is easy to handle as well as the operation is simplified, it is also suitable for batch production of the polyester fabric.
