Introduction to 3-indolycarbinol

Indole-3-Methanol is a hormone used to stimulate plant growth, which is widely used in agricultural production.

Properties of 3-indolycarbinol

Indoleacetic acid is an organic substance. The pure product Purple Sweet Potato Powder is colorless phylloid crystal or crystalline powder. Rose in light. Melting point 165-166 ℃ (168-170 ℃). Soluble in anhydrous ethanol, ethyl acetate, dichloroethane, soluble in ether and acetone. Insoluble in benzene, toluene, gasoline and chloroform. Insoluble in water, Indole-3-Carbinol its aqueous solution can be decomposed by ultraviolet light, but it is stable for visible light. Its sodium salt and potassium salt are more stable than acid itself, and are very soluble in water. It is easy to decarboxylate to 3-methylindole. It has duality to plant growth. Different parts of plant have different sensitivity to it. Generally, root is bigger than bud than stem. Different plants have different sensitivity to it.

Preparation method editor

3-Indolylcarbinol was produced by the reaction of indole, formaldehyde and potassium cyanide at 150 ℃, 0.9-1mpa, and then hydrolyzed under the action of potassium hydroxide. Or by the reaction of indole with glycolic acid. In a 3L stainless steel autoclave, add 270g (4.1mol) 85% in potassium hydroxide, 351g (3mol) indole, and then slowly add 360g (3.3mol) 70% aqueous solution of hydroxyacetic acid. Heat to 250 ℃ and stir for 18h. Cool to below 50 ℃, add 500ml of water, and stir at 100 ℃ for 30min to dissolve potassium indole 3-acetate. Cool to 25 ℃, pour the autoclave material into water, and add water to the total volume of 3L. Extract with 500ml ether, separate water layer, acidify with hydrochloric acid at 20-30 ℃, and precipitate indole-3-acetic acid. Filter, wash in cold water, dry in dark, and obtain 455-490g of the product.

Classification of thermal printers and thermal paper

Thermal Kiosk Printer can be divided into Thermal Line Dot System and Thermal Serial Dot System according to the arrangement of Thermal elements. Column thermal sensitivity is an early product, mainly used in some of the printing speed requirements are not high occasions, domestic authors have been used in their products. The line Thermal Portable Receipt Printer is a 1990s technology that prints much faster than the column thermal sensor, with the fastest speed reaching 230mm/ s. In order to realize high speed thermal printing, in addition to selecting high speed thermal printing head, the corresponding control board must cooperate with it.

58mm Thermal Printer paper is a special coating process paper, its appearance and ordinary white paper similar. Thermosensitive paper surface is smooth, is made of ordinary paper as a paper base, coated with a layer of thermosensitive hair color layer, are coated on the surface of ordinary paper, hair color layer is composed of adhesive, color agent, colorless dye (or Bluetooth Thermal Printer), not separated by microcapsules, chemical reactions in the "latent" state. When thermosensitive paper meets the hot print head, the print head where the color reagent and colorless dye that occurs chemical reaction and color, the formation of text and text.

When thermosensitive paper is placed in the environment above 70℃, thermosensitive coating starts to change color. The reason of its discoloration is related to its composition. Thermosensitive components in thermosensitive paper coating are mainly of two kinds: one is colorless dye or leucochroma dye; The other is a color reagent. This type of thermal paper is also known as bicomponent chemical thermal recording paper.

The main colorless dyes are: crystal violet lactone (CVL), fluorane system, colorless benzoimyl blue (BLMB) or spiropyran system. Commonly used as color reagent is: para-hydroxybenzoic acid and its esters (PHBB, PHB), salicylic acid, 2, 4-dihydroxybenzoic acid or aromatic sulfone and other substances.

Thermosensitive paper after heat colorless dye and color reagent chemical reaction to produce color, so use thermosensitive paper on the fax machine to receive signals to print or print directly with thermosensitive printer, text and text will be displayed. As there are many kinds of colorless dyes, so there are different colors of writing, there are blue, purple, black and so on.

About the introduction of flax seed extract

flax seed extract has the characteristics of strong pulling force, softness, good fineness, weak conductivity, fast water absorption and water dispersion, and large expansion rate. It can be used to spin high count yarn and make high-grade clothing materials.

Source(Natural Pigment)

FlaxSeed Lignans is an ancient bast fiber crop and oil crop. Flax originated in the Near East, the Mediterranean coast. As early as the Neolithic age more than 5000 years ago, Swiss Lake dwellers and ancient Egyptians had cultivated flax and used its fibers to spin clothes, and "mummies" all over Egypt were also covered with flax cloth. Oil flax is also called flax. Flax has been cultivated for at least 1000 years in China. Fiber flax was introduced from Japan in 1906. China is mainly distributed in Heilongjiang and Jilin provinces. Lignans likes cool and humid climate. Flax fiber has the characteristics of strong pulling force, softness, good fineness, weak conductivity, fast water absorption and water dispersion, and large expansion rate. It can be used to spin high count yarn and make high-grade clothing materials.

Main components

It is rich in linolenic acid, linoleic acid and other unsaturated fatty acids, especially a-linolenic acid and r-linolenic acid.
