В связи с этим увеличивается количество сырья, из которого можно получить целлюлозу, широко изучаются экономическая и экологическая эффективность его использования и свойства получаемой целлюлозы.</p><p>В работе изучен процесс получения микрокристаллической целлюлозы из лузги семян подсолнечника P63LE10 «Pioneer» (США) с использованием пероксиуксусных кислот на основе ледяной уксусной кислоты и   42%-ной уксусной кислоты с уменьшенной в два раза концентрацией. В результате исследования установлено, что выход МКЦ (МКЦ2), полученных в присутствии пероксиуксусной кислоты при вдвое меньшей концентрации уксусной кислоты выше на 3,7%, а содержание α-целлюлозы выше на 3,6%. Однако количество остаточного лигнина в нем равно 24,02%, следы аморфной структуры (следовые количества аморфных структур) определены методами ИК-спектроскопии и рентгенодифрактограммы. Напротив, хотя выход и содержание α-целлюлозы МКЦ1, полученного с использованием пероксиуксусной кислоты на основе ледяной уксусной кислоты, ниже, чем у МКЦ2, но полученный продукт характеризуется высокой степенью чистоты и высоким содержанием упорядоченных частей целлюлозы с кристаллографическая ориентация макромолекул.</p></abstract><trans-abstract xml:lang="en"><p>Currently, the obtaining and implementation of self-degradable, harmless to the nature of composite materials based on cellulose, allows to solve a number of environmental problems. In this regard, the number of raw materials sources from which cellulose can be obtained increases, the economic and environmental efficiency of its usage and the properties of the obtained cellulose can be studied. In this study, from sunflower husk (SFH)P63LE10 «Pioneer» (USA) using glacial acetic acid and based on acetic acid with 42% concentration peroxyacetic acid, process of obtaining microcrystalline cellulose comparatively was studied. As a result of the study, based on acetic acid with 42% concentration in combination peroxyacetic acid was determined, that yield of obtained MCC (MCC2) was 3,7%, and also quantity of α-cellulose was higher to 3,6%. However, the quality of the residual lignin was 24.02%, and the trace quantity of amorphous structure was determined by IR spectroscopy and XRD diffractometry. On the contrary, the yield and quantity of α-cellulose obtained MMC1 using glacial acetic acid in combination peroxyacetic acid is lower than MMC2, obtained product was different by high degree of purity and content of the ordered part of cellulose with crystallographic orientation of macromolecules.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лузга подсолнечника (SFH)</kwd><kwd>микрокристаллическая целлюлоза (МКЦ)</kwd><kwd>растворитель</kwd><kwd>пероксиуксусная кислота (PAA)</kwd><kwd>ледяная уксусная кислота</kwd><kwd>α-целлюлоза</kwd><kwd>остаточный лигнин</kwd><kwd>кристалличность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sunflower husk (SFH)</kwd><kwd>microcrystalline cellulose (MCC)</kwd><kwd>solvent</kwd><kwd>peroxyacetic acid (PAA)</kwd><kwd>glacial acetic acid</kwd><kwd>α-cellulose</kwd><kwd>residual lignin</kwd><kwd>crystallinity</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This research has been funded by the Science Committee of the Ministry of Science and Higher Education of the Republic of Kazakhstan (Grant No. АР19677542)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">https://www.agbz.ru/articles/utilizatsiya-otkhodovselskogo-khozyaystva</mixed-citation><mixed-citation xml:lang="en">https://www.agbz.ru/articles/utilizatsiya-otkhodovselskogo-khozyaystva</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Zaitseva L.
