Synthesis and efficient dyeing of anthraquinone derivatives on polyester fabric with supercritical carbon dioxide

Facile route for the synthesis and characterization of new naphtho[2,3-f]quinoxaline-dione, trione and anthra-dione derivatives

“…Using adopted scheme, a series of new anthraquinone derivatives were prepared. The described approach opens up access to several derivatives of based on anthraquinones, which can be extended for the preparation of class of compounds for different applications (Cardoso et al, 2019;Devi et al, 2020;Li et al, 2017;Nagia and El-Mohamedy, 2007;Orbán et al, 2008;Penthala et al, 2019;Ramotowska et al, 2019;Rybczyńska-Tkaczyk et al, 2018;Shan et al, 2015;Tapeinou et al, 2018;Veremeichik et al, 2019;Zarren et al, 2019;.…”

“…Natural and synthetic anthraquinones have attracted the interest of researches due to their significant biological activities such as antitumour (Chang, 2004;Ge et al, 1997, Hug et al 2004, anti-inflammatory (Yadav et al, 2010), antimalarial (Sitti et al, 1999, Yadav et al, 2010Osman et al, 2010), antimicrobial (Xiang et al, 2008, Yadav et al, 2010, antifungal (Rath et al, 1995) antileukemic Lee, 1984, Ismail et al, 1997), antiviral and anti-HIV properties (Schinazi et al, 1990, Anderson et al, 1991, Barnad et al, 1992, Alves et al, 2004. Anthraquinone and its derivatives are also used as antioxidants (Yen et L., 2000), dyes (Sokolyuk et al, 1993;Bechtold et al, 1999;Guo et al, 2007;Ahn et al, 2009) or in photoimaging (Ahn et al, 2009) along with various other applications (Atun et al, 2019;Penthala et al, 2019;Ramotowska et al, 2019;Shahid et al, 2019;Sharma et al, 2012;Tikhomirov et al, 2019;.…”

Recent advances in supercritical fluid dyeing

“…1,4,13,[24][25][26][27][28] However, laboratory-scale investigations 18,[29][30][31][32] or simulation studies 33 aimed at disclosing other aspects of the process mechanism have also been conducted, as well as tests with natural or new synthetic dyestuffs. [34][35][36][37] 2.1 | Recent technological advances (2014- Table 1 provides an overview of some recent laboratory to industrial-scale prototypes and innovative technological solutions for SFD of PET. All entries reported refer to research conducted in China, which reflects its economic growth and industrial development in the last decade.…”

“…These may be newly synthesised anthraquinone 34 or azo dyes 35 as well as natural compounds. 36,37 Researchers have reported many different reasons to search for novel dyes, such as the enlargement of the number of supercritical carbon dioxide-soluble dyes, 35 their synthesis from commercially inexpensive starting materials 34 or the employment of hypoallergenic molecules. 36,37 Other innovative purposes are the use of special dyes to impart anti-bacterial, fluorescent or photochromic properties to the textile, which is discussed in section 5.…”

“…In the above‐cited context, the academic research of recent years has often been conducted in cooperation with textile companies to improve the technology of the process, aimed at increasing the production efficiency 1,4,13,24‐28 . However, laboratory‐scale investigations 18,29‐32 or simulation studies 33 aimed at disclosing other aspects of the process mechanism have also been conducted, as well as tests with natural or new synthetic dyestuffs 34‐37 …”
