Preparation method of dioctyl sodium sulfosuccinate

The invention belongs to the technical field of fine chemical production, and discloses a preparation method of dioctyl sodium sulfosuccinate. The preparation method mainly comprises the steps of an esterification stage: implementing alcoholysis reaction to isooctanol and maleic anhydride, adding a catalyst and a color fixative, implementing primary dual-esterification reaction at 115 DEG C, increasing temperature to 185-205 DEG C and carrying out reaction to generate diisooctyl maleate; and a sulfonation stage: implementing reflux reaction to diisooctyl maleate, sodium hydrogen sulfite and water, and removing residual isooctanol in a refluxing process to obtain dioctyl sodium sulfosuccinate. The preparation method disclosed by the invention is low in isooctanol addition, thus reducing raw material cost, and is free from vacuum reaction and isooctanol removal under high vacuum, so as to greatly reduce requirement on equipment; the isooctanol is removed in the sulfonation reaction, thus effectively reducing residue. The prepared dioctyl sodium sulfosuccinate is light in color, small in smell, good in wettability and low in isooctanol content.

Single azo based pyridine ketone dye and preparation method and application thereof

The invention discloses a single azo based pyridine ketone dye and a preparation method and application thereof. The structural formula of the single azo based pyridine ketone dye is as shown in formula (I). A pyridine ring of a coupled component of the single azo based pyridine ketone dye is provided with a substituent group (the formula can be found in the description), the ether group and polyester fibers in the substituent group have good appetency, the attached dye is not prone to transference from the interior of the fibers to the surface of the fibers even at a high temperature, color change does not happen easily, other fabrics are not stained easily in the ironing process, and thermal migration fastness and sublimation fastness of the dye are greatly improved through the large molecular weight and the ether group so that fabrics can maintain good dyefastness; besides, electron withdrawing substituents such as a methoxy group, nitryl and chlorine elements are introduced to the para-position of a diazo group of the diazo component of the single azo based pyridine ketone dye, or the nitryl is introduced to the meta-position of the diazo group, so that the color of the single azo based pyridine ketone dye is deepened; meanwhile, the nitryl or the chlorine elements is / are introduced to the ortho-position of the diazo group, and the hyperchromic effect is further improved.
