摘要:
The present invention provides disazo reactive dyestuffs containing the quaternary group compounds of the general formula (1) wherein R, (W)0˜3, (W′)0˜3, Y1 and Y2 are defined the same as the specification. The dyes of the invention are distinguished by high fixation and a very good build-up. They are distinguished also by high washing off and a low nylon stain, and they have fiber-reactive properties and are very highly suitable for dyeing and printing of materials containing either cellulose fibers, such as cotton, synthetic cotton, hemp, and synthetic hemp, or amide containing fibers such as wool and nylon.

摘要:
A dye composition, which comprising: (a) an azo dye of the formula (I) wherein R, R1, R2, R3 and Y are defined the same as the specification; and (b) an azo dye of the formula (II) wherein R, R1, R2 and Y are defined the same as the specification. These kinds of dye composition with good stability and build-up. The dye composition are suitable for dyeing and printing of materials containing either cellulose fibers, such as cotton, viscose rayon, linen, and artificial linen, or synthetic polyamide, such as wool, silk, and nylon etc. Dyed materials with excellent properties can be obtained, showing especially outstanding performance in of wash-off, build-up, level-dyeing, wet fastness, ghosting fastness and light fastness.
摘要:
A dye composition is disclosed, which comprises a blue anthraquinone dye of the following formula (I) wherein Y is —CH═CH2, —CH2CH2Cl or —CH2CH2OSO3H; and a gray-black azo dye of the following formula (II) wherein Y is defined as the above. The dye compositions of the present invention have good stability and build-up property. The dye compositions are suitable for dyeing and printing materials that contain either cellulose fibers, such as cotton, artificial cotton, linen, and artificial linen, or synthetic polyamide, such as wool, silk, and nylon. The materials obtained through treatment with the dye compositions aforementioned show excellent properties, especially in wash-off, level-dyeing, build-up, light fastness and perspiration-light fastness.
摘要:

The black dye composition of present invention can be widely applied to dyeing a greater range of spinning and weaving products that contain hydroxyl group or amide group.
摘要:
A process for synthesizing N-[1-(S)-ethoxycarbonyl-3-phenylpropyl]-L-alanine derivatives of the following formula (I): ##STR1## in which the definition of R has the same meaning as given in the description by using a sulfite derivative to activate the C-terminus of the three dimensional structure of an amino acid of N-[1-(S)-ethoxycarbonyl-3- phenylpropyl]-L-alanine, which can effectively couple with another amino acid to form a dipeptide of formula (I). The compound of fomula (I) is an inhibitor of ACE.
摘要:
