Išradimo realizavimo pavyzdžiaiExamples of realization of the invention
Pagal išradimą pasiūlytas preparatas, naudojamas kaip ureazės inhibitorius, yra tirpalas, kurį sudaro N-(n-butil) tiofosforo triamidas (NBPT), ištirpintas tirpiklyje, kur minėtas tirpiklis yra tirpiklių mišinys iš glikolio eterio ir bent vieno ar daugiau gamtinių eterinių aliejų ar jų komponentų ar jų mišinių.The preparation proposed according to the invention, used as a urease inhibitor, is a solution consisting of N-(n-butyl)thiophosphoric triamide (NBPT) dissolved in a solvent, where said solvent is a solvent mixture of glycol ether and at least one or more natural essential oils or components or their mixtures.
NBPT mišinj sudaro: 15-25 sv.% NBPT (CAS N r.94317-64-3) ir 85-75 sv.% tirpiklių mišinys.NBPT mixture consists of: 15-25 wt.% NBPT (CAS No. r.94317-64-3) and 85-75 wt.% mixture of solvents.
Tirpiklių mišinį sudaro: 99 - 50 sv.% dipropilenglikolio monometilo eteris (CAS N r.34590-94-8), 1 - 50 sv.% gamtiniai eteriniai aliejai, ar jų komponentai ar jų mišiniai: kmynų (Carum carvi), arbatmedžio (Melaleuca alternifolia), eukaliptų (Eucalyptus globulus), levandų (Lavandula angustifolia), pušų (Pinus sylvestris), mėtų (Mentha arvensis), čiobrelių (Thymus žygis), mandarinų (Citrus reticulata), cinamono (Cinnamomum zeylanicum), gvazdikėlių (Eugenia caryophyllus), pankolių (Foeniculum vulgare), rozmarinų (Rosmarinus officinalis), anyžių (Pimpinella anisum) ir kt.The solvent mixture consists of: 99 - 50 wt.% dipropylene glycol monomethyl ether (CAS N r.34590-94-8), 1 - 50 wt.% natural essential oils, or their components or their mixtures: cumin (Carum carvi), tea tree ( Melaleuca alternifolia), eucalyptus (Eucalyptus globulus), lavender (Lavandula angustifolia), pine (Pinus sylvestris), mint (Mentha arvensis), thyme (Thymus jigis), tangerine (Citrus reticulata), cinnamon (Cinnamomum zeylanicum), cloves (Eugenia caryophyllus ), fennel (Foeniculum vulgare), rosemary (Rosmarinus officinalis), anise (Pimpinella anisum), etc.
Vienas iš tirpiklių mišinio komponentų pasirinktas dipropilenglikolio monometilo eteris, sumažinant NBPT preparato kenksmingumą.Dipropylene glycol monomethyl ether was selected as one of the components of the solvent mixture, reducing the harmfulness of the NBPT preparation.
Tirpiklių mišinio išskirtinumą sudaro tai, kad jo sudėtyje yra naudojami nebrangūs gamtiniai eteriniai aliejai, ar jų komponentai ar jų mišiniai (pvz. kmynų, arbatmedžio, eukaliptų, levandų), t.y. sudėtingi lakiųjų medžiagų mišiniai, kuriuos sintetina aromatiniai augalai. Eteriniai aliejai pasižymi įvairiausiu biologiniu veiklumu kaip antimikrobiniu, antioksidaciniu ir chemoprevenciniu.The uniqueness of the solvent mixture consists in the fact that it contains inexpensive natural essential oils, or their components or their mixtures (e.g. cumin, tea tree, eucalyptus, lavender), i.e. complex mixtures of volatile substances synthesized by aromatic plants. Essential oils are characterized by various biological activities such as antimicrobial, antioxidant and chemopreventive.
Ureazės inhibitoriaus NBPT preparato savybė - eterinių aliejų ar jų komponentų ar jų mišinių įtaka didesniam preparato lakumui.The property of the urease inhibitor NBPT preparation is the effect of essential oils or their components or their mixtures on the greater volatility of the preparation.
Lakiųjų komponentų masės dalis buvo nustatoma džiovinimo metodu. Trąšų granulės buvo ištirtos iškart po jų padengimo NBPT preparatu, o vėliau tiriamos po 7; 17; 34 ir 77 dienų ir rezultatai palyginami su nepadengtų NBPT preparatu trąšų granulių rezultatais.The mass fraction of volatile components was determined by the drying method. Fertilizer pellets were tested immediately after being coated with the NBPT preparation and then tested after 7; 17; 34 and 77 days and the results are compared with the results of fertilizer granules not coated with NBPT preparation.
Pavyzdys pateiktas su kmynų eteriniu aliejumi parodytas brėžinyje. 1 procentą bazinio dipropilenglikolio monometilo eterio tirpiklio pakeitus kmynų eteriniu aliejumi, iškart po trąšų granulių padengimo NBPT preparatu nustatyta lakiųjų komponentų masės dalis buvo 0,29% ir ji buvo panaši kaip nepadengtų preparatu granulių. Po 77 dienų ir padengtų NBPT preparatu, ir nepadengtų granulių lakiųjų komponentų masės dalis buvo 0,22% (brėžinyje 1 kreivė). 50 procentų bazinio dipropilenglikolio monometilo eterio tirpiklio pakeitus kmynų eteriniu aliejumi, iškart po padengimo NBPT preparatu granulių lakiųjų komponentų masės dalis buvo 0,26 % ir ji buvo mažesnė už nepadengtų preparatu granulių lakiųjų komponentų masės dalį. Po 77 dienų padengtų NBPT preparatu granulių lakiųjų komponentų masės dalis buvo 0,17 % ir ji buvo mažesnė lyginant su nepadengtomis preparatu granulėmis (brėžinyje 2 kreivė).An example with cumin essential oil is shown in the drawing. After replacing 1 percent of the basic dipropylene glycol monomethyl ether solvent with cumin essential oil, the mass fraction of volatile components determined immediately after coating the fertilizer pellets with the NBPT preparation was 0.29% and it was similar to the pellets not coated with the preparation. After 77 days, both the NBPT-coated and uncoated pellets had a mass fraction of volatile components of 0.22% (curve 1 in the figure). After replacing 50 percent of the basic dipropylene glycol monomethyl ether solvent with cumin essential oil, the volatile component mass fraction of the granules immediately after coating with the NBPT preparation was 0.26% and was lower than the volatile component mass fraction of the uncoated granules. After 77 days, the mass fraction of volatile components of the pellets coated with the NBPT preparation was 0.17% and it was lower compared to the pellets not coated with the preparation (curve 2 in the drawing).
Galima daryti išvadą, kad NBPT preparato didesnę bazinio dipropilenglikolio monometilo eterio tirpiklio dalį (iki 50 procentų) pakeitus kmynų eteriniu aliejumi lakiųjų komponentų masės dalis granulėse buvo gaunama mažesnė ir trąšų granulės buvo sausesnės.It can be concluded that after replacing a larger part of the basic dipropylene glycol monomethyl ether solvent (up to 50 percent) of the NBPT preparation with cumin essential oil, the mass fraction of volatile components in the granules was lower and the fertilizer granules were drier.
Eterinių aliejų ar jų komponentų ar jų mišinių buvimas tirpiklių kompozicijoje (mišinyje jų buvo naudota iki 50 tirpiklių mišinio masės %,) turėjo įtakos NBPT preparato lakumui - pagreitino jo lakių komponentų išgaravimą nuo trąšų granulių paviršiaus, granulės buvo sausesnės ir stipresnės.The presence of essential oils or their components or their mixtures in the composition of solvents (up to 50% of the mass of the solvent mixture was used in the mixture) affected the volatility of the NBPT preparation - it accelerated the evaporation of its volatile components from the surface of the fertilizer granules, the granules were drier and stronger.
Preparato, naudojamo kaip ureazės inhibitorius gamybos būdas. Į pritaikytą maišymui indą supila iš anksto numatytą dipropilenglikolio monometilo eterio kiekį. Į jį supila iš anksto numatytą kiekį NBPT, susmulkintą iki miltų frakcijos, irtirpina kambario temperatūroje nuolat maišant, kol ištirpsta NBPT. Maišymas gali vykti 2 vai. ir ilgiau, priklausomai nuo gaminamo NBPT preparato kiekio ir NBPT koncentracijos preparate. Po to į tirpalą supila numatytą kiekį gamtinių eterinių aliejų, ar jų komponentų ar jų mišinių ir gerai išmaišo kol tirpalas tampa homogeniškas.Method of production of a preparation used as a urease inhibitor. A predetermined amount of dipropylene glycol monomethyl ether is poured into a mixing vessel. A predetermined amount of NBPT, crushed to a flour fraction, is added to it and dissolved at room temperature with constant stirring until the NBPT dissolves. Mixing can take place 2 or. and longer, depending on the amount of NBPT preparation produced and the concentration of NBPT in the preparation. After that, the intended amount of natural essential oils or their components or their mixtures is poured into the solution and mixed well until the solution becomes homogeneous.
Preparato gamybos metu NBPT ištirpinamas tirpiklių mišinyje kambario temperatūroje be papildomo šildymo.During preparation, NBPT is dissolved in a mixture of solvents at room temperature without additional heating.
