Zhao, Xiao-yue;Xu, Huai-de;Yang, Rong-xiang published 《Optimization of fermentation conditions of green tea wine and changes in its main components during fermentation》. The research results were published in《Shipin Kexue (Beijing, China)》 in 2014.Name: 3,7-Dimethyloctan-3-ol The article conveys some information:

The fermentation process of green tea wine was optimized, and the changes in polyphenols, catechins and aroma components during fermentation were investiated. Orthogonal array experiments were used to optimize the fermentation process. The changes in catechins and aroma components were determined by high performance liquid chromatog. (HPLC) and gas chromatog.-mass spectrometry (GC-MS). The optimal fermentation parameters were determined as follows: 4 g/L green tea infusion with 20% glucose and 50 g/L honey added, 5 g/L wine yeast inoculum size, and fermentation at 28°C for 10 days. The contents of six catechins were increased during fermentation Specifically, the contents of (-)-epigallocatechin (EGC), (-)-gallocatechin gallate (GCG), epicatechin gallate (ECG), and epicatechin (EC) were slightly increased; however, the contents of catechin (C) and epigallocatechin-3-gallate catechin (EGCGC) were increased by 10.88 and 17.33-folds, resp. These results indicate that the increase of catechins plays an important role in the health-promoting function of green tea wine. There were 87, 88 and 94 aroma components in the wine at the initial and the last stages of fermentation and the aged wine, which accounted for 92.93%, 98.26% and 91.87% of the total volatile components, resp. The significant differences in the types and amounts of aroma components indicate the transition from the tea flavor to the wine aroma components. Green tea can be fermented into wine; the health-promoting components (catechins) of green tea are increased to different extents and the green tea wine is mellow. To complete the study, the researchers used 3,7-Dimethyloctan-3-ol (cas: 78-69-3) .

Dioxiranes are among the most selective and useful reagents for C(sp³)-H hydroxylation, but the development of a general dioxirane-mediated catalytic method has been an elusive goal. A trifluoromethyl ketone catalyst in combination with Oxone is shown to enable the first dioxirane-mediated catalytic hydroxylations that approx. the reactivity and selectivity of isolated dioxiranes. The mild reaction conditions allow for selective 3° hydroxylation and 2° oxidation and are tolerant of acid-sensitive functionality and electron-neutral arenes.3,7-Dimethyloctan-3-ol (cas: 78-69-3) were involved in the experimental procedure.

Safety of 3,7-Dimethyloctan-3-ol《Biogenic volatile organic compound (BVOC) emissions from various endemic tree species in Turkey》 was published in 2015.

The author mentioned the following in the article:

Compositions of biogenic volatile organic compound (BVOC) emissions from seven endemic tree species (Troy Fir, Uludag Fir, Cilician Fir, Oriental Sweetgum, Boz Pirnal Oak, Ispir Oak and Vulcanic Oak) in Turkey were determined Field samplings were carried out in the forested areas using a specific dynamic enclosure system during the summers of 2011 and 2012. The selected branches of tree species were enclosed in a chamber consisted of a transparent Nalofan bag. The air-flows were sampled from both inlet and outlet of the chamber by Tenax-filled sorbent tubes in the presence of sunlight. Isoprene, monoterpenes, sesquiterpenes, oxygenated sesquiterpenes and other oxygenated compounds including sixty five BVOC species were analyzed with a GC/MS system. Temperature, humidity, photosynthetically active radiation (PAR) and CO₂ concentrations were monitored both inside the enclosure and in ambient air. Calculated emission rates were normalized to standard conditions (1000 μmol/m² s PAR and 30 °C temperature). Ispir Oak, Oriental Sweetgum and Cilician Fir were the highest BVOC emitters with total normalized emission rates of 19.4 ± 19.2, 16.3 ± 16.1 and 15.5 ± 11.4 μg/g/h, resp. while Boz Pirnal Oak had the lowest emission rate of 0.84 ± 0.68 μg/g/h. Alpha-pinene, beta-pinene, beta-myrcene and limonene were the compounds dominating the monoterpene emission profiles while trans-caryophyllene, isolongifolene, alpha-humulene and copaene were the prominent sesquiterpenes. Predominant oxygenated compounds were also found as eucalyptol, linalool-L and alpha-terpineol. As reported in the literature, coniferous and broad-leaved species were predominantly monoterpene and isoprene emitters, resp. Oxygenated compounds were the third most prominent BVOC group and sesquiterpenes had relatively lower contributions for all species. To complete the study, the researchers used 3,7-Dimethyloctan-3-ol (cas: 78-69-3) .

Kamei, Yuji;Seino, Yusuke;Yamaguchi, Yuto;Yoshino, Tatsuhiko;Maeda, Satoshi;Kojima, Masahiro;Matsunaga, Shigeki published 《Silane- and peroxide-free hydrogen atom transfer hydrogenation using ascorbic acid and cobalt-photoredox dual catalysis》. The research results were published in《Nature Communications》 in 2021.Computed Properties of C10H22O The article conveys some information:

A silane- and peroxide-free HAT hydrogenation using a combined cobalt/photoredox catalysis and ascorbic acid (vitamin C) as a sole stoichiometric reactant was reported. A cobalt salophen complex is identified as the optimal cocatalyst for this environmentally benign HAT hydrogenation in aqueous media, which exhibits high functional-group tolerance. In addition to its applicability in the late-stage hydrogenation of amino-acid derivatives e.g., serine and drug mols., this method offers unique advantage in direct transformation of unprotected sugar derivatives e.g., (2R,3R,4R,5R,6S)-2-(hydroxymethyl)-6-(2-methylallyl)tetrahydro-2H-pyran-3,4,5-triol and allows the HAT hydrogenation of unprotected C-glycoside e.g., ((2R,3S,4R,5S)-3,4-dihydroxy-5-(2-methylallyl)tetrahydrofuran-2-yl)methyl acetate in higher yield compared to previously reported HAT hydrogenation protocols. The proposed mechanism is supported by exptl. and theor. studies. To complete the study, the researchers used 3,7-Dimethyloctan-3-ol (cas: 78-69-3) .
