What are the characteristics of Schiff base, such as chelation, heat resistance, liquid crystal and intrinsic conductivity. The conductivity of Conjugated Poly (Schiff base) doped with iodine can be increased by about 8 orders of magnitude, which makes it reach the level of semiconductor. The doped materials have good stability, electrochemical activity and photoconductivity. In the conventional state, the molecular chain of poly (Schiff base) is relatively rigid, and the intermolecular force is also strong, so the polymer is insoluble and insoluble. However, the Schiff base synthesized by using trimethylol aminomethane and other solvents directly makes the Schiff base get rid of the difficult situation of polymer processing and characterization, and the conductivity increases. In order to improve the yield of Schiff base, it is necessary to synthesize Schiff base by the reaction of 3,5-dibromosalicylic aldehyde with trimethylolminomethane, and reduce Schiff base with anhydrous ethanol at room temperature. The results showed that the molar ratio of 3,5-dibromosalicylic aldehyde to trihydroxymethylaminomethane was 1 â?¶ 1, the reaction time was 30 min, the molar ratio of sodium borohydride to 3,5-dibromosalicylic aldehyde trihydroxymethylaminomethane Schiff base was 1.5 1, and the yield of reduced Schiff base was 81.4%.

Product name High Effective Pure Glucose Powder, Additives In Blood Tubes CASã??50-99-7 Appearance Colorless Transparent Powder MOQ 1kg Usage Moisture Molecular Formula CH2OH(CHOH)4CHO+2Ag(NH3)2OH Properties White Powder Glucose, organic compound, molecular formula C6H12O6. It is the most widely distributed and most important monosaccharide in nature. It is a polyhydroxy aldehyde. Pure glucose is colorless crystal, sweet but not as sweet as sucrose (can not taste sweet), soluble in water, slightly soluble in ethanol, insoluble in ether. The natural glucose aqueous solution is optically responsive to the right, so it belongs to "dextrose". Glucose plays an important role in the biological field. It is the energy source of living cells and the metabolic intermediate, the main energy-generating substance of living things. Plants produce glucose through photosynthesis. It is widely used in the field of candy manufacturing and medicine. Chemical properties It is the most widely distributed monosaccharide in nature. Glucose contains five hydroxyl groups, one aldehyde group, having the properties of a polyol and an aldehyde. It is easily decomposed by heating under alkaline conditions. It should be kept in a sealed state. It is quickly absorbed after oral administration and is used by tissues after entering the human body. After 1kg of glucose is completely oxidized by the human body, 2870KJ of energy is released. Some of this energy is converted into 30 or 32mol of ATP. The rest of the energy is released as heat to maintain body temperature. It can also be converted into glycogen or fat by liver or muscle. (1) The aldehyde group in the molecule is reducible and can react with silver ammonia solution: CH2OH(CHOH)4CHO+2Ag(NH3)2OH-water bath heatingCH2OH(CHOH)4COONH4+2Ag+3NH3+H2O, oxidized Into ammonium gluconate. (2) The aldehyde group can also be reduced to hexahexol. (3) There are a plurality of hydroxyl groups in the molecule, which can be esterified with an acid. (4) Glucose undergoes an oxidation reaction in the living body, releasing heat (C6H12O6 + 6O2 (oxygen) + 6H2O = = 6CO2 + 12H2O + energy). (5) Glucose can be obtained by hydrolysis of starch under the action of enzyme or sulfuric acid. (6) Plant photosynthesis: 6CO2+6H2O (chlorophyll, sunlight catalysis) - C6H12O6+6O2. (7) Reaction equation between glucose and new copper hydroxide: CH2OH(CHOH)4CHO+2Cu(OH)2-heated->CH2OH(CHOH)4COOH+Cu2O+2H2O. (8) Glucose is decomposed into water and carbon dioxide under certain conditions. (9) Hydrolysis of maltose: C12H22O11+H2O-catalyst2CH2OH(CHOH)4CHO (10) Starch and cellulose hydrolysis: (C6H10O5)n+nH2O-catalystnCH2OH(CHOH)4CHO
Coriander Seeds : Most people perceive the taste of coriander leaves as a tart, lemon/lime taste, but a smaller group, of about 4 14% of people tested, think the leaves taste like bath soap, as linked to a gene which detects aldehyde chemicals also present in soap.
Cinnamon, and its relative cassia, have long been prized for both flavor and medicine. Romans used cinnamon to make their strong, bitter wine palatable, Greeks to season meat and vegetable dishes, Arabs in tea, and nearly everyone in baked goods. English nobility hoarded to delicate Ceylon cinnamon to flavor breads and puddings. Fragrant cinnamon spice is one of the highly prized spices that has been in use since biblical times for its medicinal and culinary properties. This delightfully exotic, sweet-flavored spice stick is traditionally obtained from the outer brown bark of Cinnamomum trees, which when dried, rolls into a tubular form known commercially as quill. The cinnamon plant is a small, evergreen bushy tree belonging to the family of Lauraceae or laurel within the genus; Cinnamomum. This novel spice is native to Sri Lankan island but also found in many other countries such as Myanmar, Bangladesh, India, China, and Indonesia. Varieties of the cinnamon tree exist; however, Sri Lankan variety is regarded as true cinnamon and scientifically named as Cinnamonum verum. Traditionally, the inner bark is bruised with a brass rod, peeled and long incisions are made in the bark. It is then rolled by hand and allowed to dry in the sunlight. It is the bark of the tree from where aromatic essential oil (makes up 0.5% to 1% of its composition) is extracted. Usually, the oil is processed by roughly pounding the bark, macerating it in seawater, and then quickly distilling the whole. The oil features golden-yellow color, with the characteristic odor of cinnamon and a very hot aromatic taste. The pungent taste and scent in cinnamon spice are due to compound cinnamic aldehyde and cinnamaldehyde in the oil. Cassia, also known as chinese cinnamon, is a different member of Lauraceae family and named as Cinnamomum cassia. Cassia is coarser, more spicy, and pungent but less fragrant than cinnamon. It is usually substituted for the cinnamon in savory dishes.
