Peroxyde d'hydrogèneLe peroxyde d'hydrogène (H2O2), communément appelé eau oxygénée ou encore perhydrol (appellation industrielle), est un composé chimique liquide et visqueux, aux puissantes propriétés oxydantes (il est aussi réducteur). C'est donc un agent blanchissant efficace qui sert de désinfectant et (à haute concentration) d'oxydant ou monergol dans les fusées spatiales.
ZéolitesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The Fenton-like oxidation of CI Reactive Red 141 was investigated over iron-containing ZSM-5 zeolites. Iron was loaded by ion exchange or through hydrothermal synthesis. The oxidation process was carried out in an aqueous solution using hydrogen peroxide as the oxidant. The catalyst prepared by ion exchange with a silicon/aluminium ratio of 42 zeolite showed the highest activity (97% decolorisation and 52% chemical oxygen demand reduction at an initial pH of 3.5) after an oxidation duration of 2 h. The chemical oxygen demand reduction increased with the increasing amount of iron loaded to the zeolite. The FeZSM-5 catalyst, prepared by hydrothermal synthesis in the presence of oxalic acid, showed very good activity in terms of mineralisation (99% of chemical oxygen demand reduction). The iron leaching was noticeably low (below the European Union directives of 2 mg dm−3) for the above-mentioned catalysts.

Colorants dispersésCatégorie de colorants très peu solubles dans l'eau, utilisés à l'origine comme colorants pour l'acétate, et qui généralement sont appliqués sous forme de suspensions aqueuses de faible concentration.Les colorants dispersés sont largement utilisés dans la teinture de la plupart des fibres manufacturées, surtout le polyester.
Colorants réactifs
DiazirinesLes diazirines sont une classe de molécules organiques constituées d'un carbone lié à deux atomes d'azote, qui sont doublement liés l'un à l'autre, formant un cycle de type cyclopropène , le 3H -diazirène. Ils sont isomères avec les groupements diazocarbonés , et comme eux peuvent servir de précurseurs aux carbènes par perte d'une molécule de diazote . Par exemple, l'irradiation des diazirines avec de la lumière ultraviolette conduit à l'insertion de carbène dans diverses liaisons CH, NH et OH. Par conséquent, les diazirines ont gagné en popularité en tant que petits réactifs de réticulation photoréactifs. Ils sont souvent utilisés dans le marquage par photoaffinitéétudes pour observer une variété d'interactions, y compris les interactions ligand-récepteur, ligand-enzyme, protéine-protéine et protéine-acide nucléique.

Textiles et tissus -- Propriétés mécaniquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The dyeing of polypropylene fabrics utilising conventional-disperse dyes often meets poor colour yield and fastness problems, fundamentally caused by the low affinity between dyes and polypropylene fibres. In this article, a new class of hydrophobic reactive dyes that can react with polypropylene were designed using diazirine moiety as a reactive group, azo structure as a chromophore, and an ester group as a linking bridge. The difference among these dyes was the alkyl chain length on the azo chromophore, which was used to fine-tune the affinity between the dyes and fibre. The structures of the synthesised dyes and intermediates were characterised and confirmed using nuclear magnetic resonance, mass spectrometry, and infrared spectrometry. The absorption and thermal properties of the dyes were also studied to ensure their feasibility for dyeing application. In addition, the diazirine dyes were successfully applied to dye polypropylene fabrics using a two-step process by dyeing in a non-aqueous solvent and fixing it under heating. The dyes and polypropylene fibre were demonstrated to react, where the fixation values were in the range 64.5–76.4%. The systematic study of the structure–property relationship demonstrated the positive effect of the alkyl chain in promoting colour yield, however, accompanied by a slightly reduced fixation value. Due to the chemical bonding of the dye molecules to the fibre, the dyed polypropylene fabrics exhibited excellent colour fastness property, making the dyeing technology very promising for future industrial applications.

Spectrophotométrie UV-VisibleIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : One of the main environmental problems in the leather industry is the contaminant load and amount of effluent produced during the industrial process. From these effluents we can highlight those resulting from the dyeing processes that contribute to the increase of the COD and BOD of the discharged wastewaters. The aim of the present work is to develop and validate simple, rapid, specific, selective, precise, robust and economical UV-Vis Spectrophotometric method for the estimation of reactive dye (Navy Blue Her) in aqueous solutions and effluents of the dyeing processes of chrome-tanned leather. UV-Vis Spectrophotometric measurement was carried out at a wavelength of maximum absorbance of 610 nm using ultrapure water as the solvent. The developed method was validated with respect to specificity, selectivity, sensitivity, limits of detection and quantification, linearity, precision (repeatability, intermediate precision) and robustness. The calibration curve (Abs = 0.01054C + 0.00067) is linear (r2 = 0.99998) in the concentration range from 3.0 mg/L up to 48.0 mg/L. The limit of detection (LOD) and the limit of quantification (LOQ) are 0.206 mg/L and 0.624 mg/L, respectively. The analysis results and its statistical treatment have proved that this analytical method is specific, selective, precise and robust, and has good repeatability and intermediate precision. Thus the proposed method was approved for all the analyzed parameters, being therefore, properly validated, and can be successfully applied for the estimation of reactive dye (Navy Blue Her) in aqueous solutions and effluents of the dyeing processes of chrome-tanned leather.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : This review describes the immense impact of reactive dyes on the textile industry. Their use on cellulosic fibres is especially important, but their growing popularity on polyamide substrates is notable. Detailed information is given about developments both in the chemistry of reactive systems and in the chemical technology involved in their application to a variety of fibre types. It is also pointed out that further research is necessary to improve dye–fibre fixation efficiency, especially when dyeing full shades on cellulosic fibres. This work is necessary to address the current environmental problem of colour in dyehouse effluent. The potential solutions reviewed include multifunctional reactive dyes, cationic reactive dyes, and cellulose fibre modification.

Spectrométrie de masseIndex. décimale : 667.2 Colorants et pigments Résumé : As part of an approach to enhancing the efficiency of reactive dye adsorption on cellulosic fibres at low electrolyte levels, commercially available dyes were dimerised using hexamethylenediamine (HMDA) as a linking group. A key component of this work involved using high-resolution mass spectrometry (HRMS) to characterise a group of polysulphonated heterobifunctional monochlorotriazine/vinyl sulphone reactive dyes (CI Reactive Yellow 176, CI Reactive Red 239, CI Reactive Blue 221, CI Reactive Red 194 and CI Reactive Blue 222) and their dimeric analogs. In this respect, dimeric dye ions of differently charged states were observed using HRMS-negative electrospray ionisation in combination with quadrupole time-of-flight mass spectrometry. For example, HRMS showed that the HMDA-linked reaction products were mixtures of the target (unhydrolysed) dimers, hydrolysed dimers, monoreacted products and hydrolysed unreacted dyes, with CI Reactive Yellow 176 and CI Reactive Red 194 producing the desired unhydrolysed dimers.
