Abstract

The invention relates to the field of photocuring functional new material chemicals, and discloses a high performance liquid phase streamline type continuous automatic production technology of an acylphosphine oxide organic phosphine compound for the first time, which not only can produce a single specific target product, but also can co-produce a product mixture of two or more than two of the products of the type. The process technology has outstanding low-cost economic competitiveness and environment-friendly characteristics for large-scale manufacturing of target products. The target product comprises sym-trimethylbenzoyl diphenyl phosphine oxide (also known as 2, 4, 6-trimethylbenzoyl diphenyl phosphine oxide, trade name TPO), sym-trimethylbenzoyl phenyl ethyl phosphonate (trade name TPO-L) and structural analogues thereof, and a mixture of the sym-trimethylbenzoyl diphenyl phosphine oxide and the sym-trimethylbenzoyl phenyl ethyl phosphonate. The organic phosphine compound is an olefinic bond-containing (C=C) unsaturated radiation polymerization system photoinitiator and / or flame retardant and the like with wide application.

Description

[Technical field]

[0001] The present invention relates to the field of new material chemicals in photocurable function, and a high-performance liquid phase flow line continuous automation production technology of a kind of acylphophosphine oxide organic phosphine compound is disclosed, which can produce a single-specific target product. The type of product mixture of two or more of the two or more. The process technology has highlighted low-cost economic competitiveness and environmentally friendly characteristics for large-scale manufacturing of target products. The target product includes average trimethylbenzoyl diphenyl oxide (also known as "2,4,6-trimethylbenzoyl diphenyl phosphine", trade name TPO) and average trimethylbenzene Formylphenylphosphonic acid ethyl ester (trade name TPO-L) and its structural analogs, and mixtures thereof. This type of organic phosphine compound is a widely used hydroken bond (C = C) unsaturated radiation polymerization system photosensitive initiator...
