Description
Vynález sa týká spdsobu přípravy hnojivá obsahujúceho titán alebo titán a železo reakciou rozpustnej zlúčeniny titánu alebo titanu a železa, kyseliny citrónovej a amoniaku.The invention relates to a process for the preparation of a fertilizer containing titanium or titanium and iron by reaction of a soluble titanium or titanium-iron compound, citric acid and ammonia.
Biologická doležitosf titánu vo výživě rastlín nebola donedávna takmer v žiadnej odbornéj literatúře spornínaná a tento prvok bol považovaný za biologicky neúčinný, za balastný prvok.The biological importance of titanium in plant nutrition has until recently been disputed in almost no scientific literature, and this element was considered to be biologically ineffective, a ballast element.
Toto hodnotenie je prekvapujúce najma preto, lebo titán, podobné áko železo, je jedným z najviac zastúpených prvkov v zemskej koře. Z 88 prvkov vyskytujúcich se, v zemskej kóre sa zaračuje na 10.mies te před tak dóležitými živinami ako sú dusík, fosfor, síra, mangán a zinok.This assessment is surprising especially because iron-like titanium is one of the most abundant elements in the earth's root. Of the 88 elements occurring in the earth's crust, the 10th place in front of such important nutrients as nitrogen, phosphorus, sulfur, manganese and zinc.
Relativné vysoký obsah titánu v podach vulkanického povodu naznačuje, že v minulosti sa tento prvok významné zúčastňoval chemických a biologických procesov v zemskej koře.The relatively high titanium content of the volcanic basin suggests that in the past this element has been significantly involved in the chemical and biological processes in the earth's crust.
V podach sa vyskytuje prevažne vo formě silikátov, ktoré sú pre rastliny takmer neresorbovatelné. Najznámějšími prírodnými zdrojmi titánu sú minerály rutil, perowskit, illmenit, pseudobrookit a pod.It is predominantly in the form of silicates, which are almost non-resorbable to plants. The most famous natural sources of titanium are the minerals rutile, perowskite, illmenite, pseudobrookite and the like.
V relativné vysokej koncentrácii /cca 7 % T±02/, sa nachádza aj v hematite. V týchto prírodných zdrojoch je titán takmer vždy spre vádzaný železom.It is also present in hematite at a relatively high concentration (about 7% T ± 0 2 ). In these natural sources, titanium is almost always accompanied by iron.
Napriek tomu, že v súčasnej době nie sú názory na potřebu titánu pre výživu rastlín jednotné a fyziologická funkcia tohto prvku nie je úplné objasněná, výsledky výskumu za posledných 20 rokov potvrdzujú pozitivně účinky titánu pri tvorbě chlorofylu a syntéze proteínov, ako aj pri fotosyntéze.Although there is currently a lack of uniform opinion on the need for titanium for plant nutrition and the physiological function of this element is not fully understood, research results over the last 20 years confirm the positive effects of titanium in chlorophyll formation and protein synthesis as well as photosynthesis.
Konishi a Tauge zistili, že titanát draselný má priaznivý vplyv na vývoj lucerny, ako aj na množstve a aktivitu kořenových uzlin. Troitsky pozoroval priaznivý vplyv titánu pri pěstovaní viniČa, Rutskaja a Ryžabskaja zaznamenali kladný vplyv titanýlsulfátu na rast a cukornatosť cukrovej řepy. Okrem toho sa zistilo, že foliár nou aplikáciou postrekcv’ cbsahujúcich ti tán sa významné podporuje — 2 —Konishi and Tauge found that potassium titanate has a beneficial effect on lantern development as well as on the amount and activity of root nodes. Troitsky observed the beneficial effect of titanium on vine growing, Rutskaja and Ryzhabskaya noted the positive effect of titanium sulphate on sugar beet growth and sugar content. In addition, it has been found that the foliar spray application containing tannin is significantly supported - 2 -
234 348 aktivita enzýiaov nitrátoreduktázy, katalázy a polyfenol-oxidázy, Mimoriadne priaznivé výsledky na úrodu sa zaznamenali pri foliárnej aplikácii titánu na jabloniach, rajčinách a vinici /Pais a spol./.234 348 nitrated reductase, catalase and polyphenol oxidase enzyme activity. Extremely favorable crop yields have been reported with foliar application of titanium to apple trees, tomatoes and vines (Pais et al.).
Wakamoto a Tsukamoto zistili, že zlúčeniny obsahujúce titán a železo sa vyznačujú vlasnosťami inhibítorov denitrifikácie, čím sa podporuje cirkulácia dusíka v pode.Wakamoto and Tsukamoto found that compounds containing titanium and iron are characterized by the properties of denitrification inhibitors, thereby promoting nitrogen circulation in the pod.
Sposob přípravy komplexných zlúčenín s obsahom titánu a zirkonu na báze cyklopentadienylu popisuje Mrowca /US. pat. 3 728J65/. Vzhladom na zložitosť ich syntézy sa napriek pozitívnym účinkom pri pěstovaní pšenice neočákava širšie použitie týchto komplexov v polnohospodárstve /Pyziol. rastl. 22, 1177 - 1182/1975/ /· Grižanková a Bojčenko izolovali z niektorých mořských rastlín zlúčeniny titánu, predbežne nedefinovaného zloženia, u ktorých predpokladajú biologickú aktivitu. Tí istí autoři popisujú spdsob přípravy Ti-zlúčenín na báze kyseliny pentoténovej.A process for the preparation of complex compounds containing titanium and zirconium based on cyclopentadienyl is described by Mrowca / US. pat. 3,728J65 /. Due to the complexity of their synthesis, despite the positive effects in wheat cultivation, the widespread use of these complexes in agriculture / Pyziol is not expected. increased. 22, 1177-1282 (1975). Grižanková and Bojčenko isolated titanium compounds, of a predefined composition, from which they predict biological activity from some marine plants. The same authors describe a process for preparing Ti-compounds based on pentothenic acid.
Pais a spol. majú patentovo chráněný prípravok obsahujúci titán na báze titanyl-l-askorbátu, ktorý je vhodný pre výživu rastlín a vyrába sa v MÍR pod komerčným názvom Titavit” s obsahom cca 1 g Ti v 1 1 roztoku.Pais et al. have a patented titanyl-1-ascorbate-containing titanium composition which is suitable for plant nutrition and is produced in MIR under the commercial name Titavit, containing about 1 g Ti in 1 L solution.
Teraz sa zistilo, že hnojivo obsahujúce titán alebo titán a železo je možné připravit sposobom podía vynálezu.It has now been found that a fertilizer containing titanium or titanium and iron can be prepared according to the process of the invention.
Podstata vynálezu spočívá v tom, že 1 hmotnostný diel rozpustnej zlúčeniny titánu sa nechá reagovat s 2 až 18 hmotnostnými dielmi, s výhodou so 4,39 až 8,7θ hmotnostnými dielmi kyseliny citrónovej a súčasne alebo po reakcii s kyselinou citrónovou sa reakčná zmes nechá reagovat s amoniakom v takom množstve, aby výsledné pH reakčnej zmesi bolo 4,5 až 8,0, s výhodou 6,5 až 7,0.The principle of the invention is that 1 part by weight of a soluble titanium compound is reacted with 2 to 18 parts by weight, preferably 4.39 to 8.7 parts by weight of citric acid, and simultaneously or after reaction with citric acid, the reaction mixture is reacted with ammonia in an amount such that the resulting pH of the reaction mixture is 4.5 to 8.0, preferably 6.5 to 7.0.
Pre přípravu stopového hnojivá podía vynálezu je výhodné použit ako rozpustné soli titánu například titanylsulfát z výroby titánovej běloby, ktorý popři titane obsahuje aj železo. Calej sa zistilo, že okrem plynného amoniaku v záujme získania stabilného kvapalného stopového hnojivá s nízkou teplotou kryštáližácie, je výhodné použiť zriedené vodné roztoky amoniaku.For the preparation of the trace fertilizer according to the invention, it is advantageous to use as soluble salts of titanium, for example, titanyl sulfate from the production of titanium white, which in addition to titanium also contains iron. It has also been found that, in addition to ammonia gas, in order to obtain a stable liquid trace fertilizer with a low crystallization temperature, it is advantageous to use dilute aqueous ammonia solutions.
V zmysle vynálezu je spdsob přípravy stopového hnojivá obsahujúceho len titán identický so sposobom přípravy stopového hnojivá obsahujúceho titán a železo.For the purposes of the invention, the method of preparing a trace fertilizer containing only titanium is identical to the method of preparing a trace fertilizer containing titanium and iron.
Kyselina citrónová viaže titán, resp. titán a železo do komplexnej formy a umožňuje, v závislosti od jej přidaného množstva, zís- 3 234 349 kať kvapalné stopové hnojivo obmedzene alebo neobmedzene miešateíné nielen s kvapalnými dusíkatými, ale aj dusíkato-fosforecnými hnojivámi.Citric acid binds titanium, respectively. titanium and iron into a complex form and, depending on the amount added, make it possible to obtain a liquid trace fertilizer with limited or unlimited miscibility not only with liquid nitrogen but also with nitrogen-phosphorus fertilizers.
Spósobom podlá vynálezu je možné pripraviť kvapalné hnojivo s relativné vysokým obsahom titánu /maximálně 1,7 hmot. % Ti v roztoku/, ktoré je možné považovat za koncentrát titánu.According to the invention, it is possible to prepare a liquid fertilizer with a relatively high titanium content / maximum 1.7 wt. % Ti in solution, which can be considered a titanium concentrate.
