Title: Process for the preparation of bright violet dyestuffs of the anthraquinone series
IPC: C09B1/54
Filed: 1950-05-25
Abstract: The invention comprises bright violet dyes which are fast to fulling consisting of sulphonation products of compounds of formula <FORM:0678983/IV (c)/1> where A is H or Me, B is H or, when A is Me B may also be Me and R is a saturated aliphatic or cycloaliphatic hydrocarbon radical containing 4 to 8 C atoms.  They are made by heating a compound of formula <FORM:0678983/IV (c)/2> where A and B are as above and X is Br or SO3H or an alkali metal salt of SO3H, with phenols which are substituted by a saturated aliphatic or cycloaliphatic hydrocarbon radical containing 4 to 8 C atoms, in the presence of acid binding agents, and sulphonating the ensuing dyestuff.  Phenols specified are p-tert. butyl-, p-sec. amyl, p-tert. amyl, p-cyclohexyl and p-isooctyl phenol.  Diluents such as nitrobenzene, di-p-tert.-butyl-p-cresol or methylhexaline may be present.  Acid binding agents specified are hydroxides, carbonates and acetates of alkali metals advantageously those of sodium or potassium. Temperatures for completion of the condensation are about 200 DEG  C. although lower temperatures, e.g. 140 DEG  C. may be used.  When 2-bromo compounds are reacted the formation of higher molecular weight compounds is obviated by an increased concentration of alkali.  The dye bases are isolated on dilution with alcohol or on pouring into warm dilute caustic soda solution.  Sulphonation is effected in sulphuric acid monohydrate at 20-50 DEG  C.  In examples the bases from the following condensations are sulphonated: (1) p-tert.-butyl phenol and the condensation product of 1-amino-2-sulpho-4-brom-anthraquinone with mesidine; (2) p-isooctyl phenol and 1-amino-2-brom-4-mesidino-anthraquinone; (3) p-isooctyl phenol and the sodium salt of 1-amino-2-sulpho-4-mesidinoanthraquinone; (4) p-tert.-amyl phenol and the condensation product of 1-amino-2-sulpho-4-brom-anthraquinone and vic.-m-xylidine; (5) p-sec. amyl phenol and the sodium salt of 1-amino - 2 - sulpho - 4 - vic. - m - xylidinoanthraquinone; (6) p-cyclohexyl phenol and the sodium salt of (5); (7) p-tert.-butyl phenol and the condensation product of 1-amino-2-sulpho-4-brom-anthraquinone with isoduridine; (8) p-tert.-amyl phenol and the sodium salt of 1-amino - 2 - sulpho - 4 - isoduridino - anthraquinone; (9) p-tert.-amyl phenol and 1-amino - 2 - brom - 4 - mesidino - anthraquinone; (10) p-tert.-butyl phenol and the sodium salt of 1 - amino - 2 - sulpho - 4 - vic. - m - xylidinoanthraquinone; (11) p(isooctyl phenol and the sodium salt of (10); (12) p-cyclohexyl phenol and the sodium salt of 1-amino-2-sulpho-4-mesidino-anthraquinone, and (13) p-sec.-amyl phenol and the sodium salt of (12).

Title: A method of pigmenting high molecular weight synthetic plastics, and apparatus for performing the method
IPC: D01D11/00
Filed: 1966-03-28
Abstract: <FORM:1106167/C3/1> A high molecular weight synthetic plastics material is pigmented by extruding the plastics material in the molten state into a container in the form of filaments, fibres or ribbons thereof, contacting said filaments, fibres or ribbons in the container, while they are still in the molten state, with a finely divided pigment suspended in a gas which is inert to the pigment and plastics material so that the particles of pigment adhere to the filaments, fibres or ribbons, allowing said filaments, fibres or ribbons, to reunite and coalesce in the container, and withdrawing the thus pigmented plastics material from the container. Specified carrier gases include air and nitrogen and the pigment may be an inorganic pigment (e.g. titanium dioxide, zinc oxide, cadmium sulphide, lithopone, an iron oxide, a chromium oxide or carbon black), a metallic pigment (e.g. lead or zinc powder), and/or an organic pigment (e.g. a phthalocyanine).  A fluorescent pigment may be used, optionally in admixture with another pigment. Preferably the high molecular weight synthetic plastics material is a linear fibreforming polycondensate, e.g. polyethylene glycolterephthalate or a polyamide e.g. polycaprolactam, polyhexamethylene adipamide, polyundecanamide, or polylauryl lactam.  In addition to the pigment, other additives may be present e.g. optical brighteners, optical stabilizers, thermal stabilizers, flammability surpressing agents, fillers or extenders, and hydro-phobing agents.  The method may be performed continuously, and all or part of the pigmented plastics material may be recycled and submitted to a repeated similar treatment. Elevated temperatures and/or elevated or reduced pressures may be used.  In the operation of the apparatus shown, a polymerization product which is to be pigmented is introduced into the closed container 1 at 2 and is extruded through nozzle 3 in the form of filaments, fibres or ribbons which are recombined in the bottom 4 as a homogenous melt.  The apparatus is heated by external heating means 5.  A carrier gas obtained from pressurized container 6 flows through valve 7, flowmeter 8 and drying and purifying tower 10 to jet mixer, 10, which at the same time is continuously supplied with pigment from storage bin 11 via shoot 12. The pigment-laden gas stream enters container 1 at 13, ascends the apparatus and leaves at 14, a fan 15 returning it to jet mixer 10. The molten pigmented plastics material may be removed through outlet 16.  Examples relate to the pigmenting of polyethylene glycol terephthalate chips with titanium dioxide and with carbon black.
