The present application provides a comfortable lightweight bullet-proof and stab-resistant suit and a preparation method thereof. A first aspect of the present application provides a comfortable lightweight bullet-proof and stab-resistant suit, including a sheath and a protection core sheet disposed in the sheath, and the protection core sheet includes a first protection layer, a second protection layer, a third protection layer and a buffer layer which are sequentially stacked together. The bullet-proof and stab-resistant suit provided in the present application has better response protection characteristics in the process of bullet penetration or knife tip stab, and the prepared aramid unidirectional cloth has low areal density, apparent flatness, no bubbles, and excellent softness, so that any bending within 180° can be realized.

Comfortable lightweight bullet-proof and stab-resistant suit and preparation method thereof

A method for preparing 2-alkylanthracene includes the step of separating 2-alkylanthracene from a reaction product of anthracene alkylation reaction. The anthracene alkylation reaction is a reaction of anthracene and an alkylation reagent under an alkylation condition and in the presence of an alkylation reaction solvent and a catalyst. The reaction product of the anthracene alkylation reaction contains anthracene and the product of a series of alkylanthracenes containing 2-alkylanthracene.

Method for separating 2-alkylanthracenes and use thereof for producing hydrogen peroxide

The present invention relates to an N-substituted-phenyl-5-substituted-alkoxy-2,3-dihydro-[1,4]dioxane[2,3-f]quinazolin-10-amine (I) or 4-substituted-arylamino-6-substituted-alkyl-6H-[1,4]oxazino[3,2-g]quinazoline-7(8H)-one (II) type compounds, a preparation method thereof and an application thereof as an inhibitor for epidermal growth factor receptor (EGFR) (comprising some mutant forms of EGFR) to treat cancer. These compounds and salts thereof can be used to treat or prevent various cancer diseases.
