Pare, Ashay; Modi, Yashwant Kumar; Rai, Harsh Vardhan published the artcile< Environmental impact comparison of binder systems for sand moulding process using cradle-to-grave approach>, Quality Control of 71195-85-2, the main research area is binder sand molding cradle grave approach environmental impact.

Growing demand for preservation of environment, conservation of resources and development of a sustainable society is driving manufacturers to make “”greener”” products and use “”greener”” processes. Foundry is considered one of the most environment polluting industries all over the world. The work presented in this paper compares environmental impacts of sand molding process for four different binder systems, namely phenolic urethane no-bake, phenolic ester no-bake, phenolic formaldehyde and furan no-bake using a cradle-tograve life cycle assessment (LCA) approach. The comparison is made using various impact categories, such as global warming, acidification, ecol. toxicity, eutrophication, human toxicity and photochem. smog by ISO-FRED-14040 LCA method. Results of the study show that the phenolic urethane is most and the furan no bake binder is least harmful to environment and human health in most of the categories. Emissions from the phenolic ester nobake binder system are most dangerous for human health. This study also revealed that the raw material acquisition phase consumes major portion of life cycle energy for mold making process.

Application of 6290-49-9,Some common heterocyclic compound, 6290-49-9, name is Methyl 2-methoxyacetate, molecular formula is C4H8O3, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

Example 1 (Z)-3-(4-amino-3-chloro-5-trifluoromethyl-phenyl)-2-methoxy-acrylic acid (C) 26.14 kg (55.91 mol) potassium tert.butoxide solution in THF were metered into a mixture of 10.00 kg (44.73 mol) 4-amino-3-chloro-5-trifluoromethylbenzaldehyde (A), 9.31 kg (89.45 mol) methyl methoxyacetate (B) and 30.0 L tetrahydrofuran and the mixture was stirred for 24 hours at 20 C. Then 7.16 kg (89.45 mol) sodium hydroxide solution (50%) were metered in and the mixture was heated to 30 C. for 1 hour, before 16.31 kg (134.18 mol) hydrochloric acid (30%) and 15.0 L water were added. After the aqueous phase has been separated off, 40 L of the solvent were distilled off and the residue was combined with 25.0 L toluene, before another 40 L solvent were distilled off. The organic phase was combined with 20.0 L water and cooled to 23 C. After the addition of 10.0 L toluene the suspension was stirred for a further 30 minutes, the product was separated off and dried. Yield: 10.05 kg (76% of theory) Melting point: 173 C.

The synthetic route of 6290-49-9 has been constantly updated, and we look forward to future research findings.

Reference of 314298-22-1,Some common heterocyclic compound, 314298-22-1, name is Methyl 5-bromo-4-fluoro-2-methoxybenzoate, molecular formula is C9H8BrFO3, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

Cool in ice a solution of the product of Step 2 (1.15 g, 4.1 mmol) in THF (15 ml). Add dropwise BH3.Me2S (2.0M in THF, 4.2 ml, 8.4 mmol). Heat at 60 C. 18 h, allow to cool, quench with methanol, concentrate and partition with EtOAc and sat. NaHCO3. Wash with water, then brine, dry (MgSO4) and concentrate to obtain the alcohol as a yellow oil.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Methyl 5-bromo-4-fluoro-2-methoxybenzoate, its application will become more common.
